CHARLOTTE — Get ready for an all-out brawl in 10 too-close-to-call battleground states as President Barack Obama and Mitt Romney begin a two-month sprint to Election Day.
They will deluge those states with personal visits, stacks of direct mail, automated phone calls and an unprecedented barrage of TV ads in tossup states Florida, New Hampshire, Virginia, North Carolina, Wisconsin, Iowa, Colorado, Nevada, Michigan and Ohio.
Theyll probably all but ignore the rest of America.
Florida and Ohio may matter most. No Republican has won the presidency without winning Ohio, and Floridas 29 electoral votes more than 10 percent of the 270 needed to win are the biggest swing state prize.
The candidates will be dueling for support from a relative handful of undecided voters. In Ohio, for instance, RealClearPolitics poll average shows Obama up by 0.7 percentage points roughly 40,000 people in a state where 5.7 million voted for president last time.
This intense dash to Nov. 6 could well be decided in a series of debates next month. The presidential candidates are scheduled to face off Oct. 3 in Denver, Oct. 16 in Hempstead, N.Y., and Oct. 22 in Boca Raton, Fla.
Vice presidential candidates Joe Biden and Paul Ryan debate Oct. 11 in Danville, Ky. All debates will run from 9-10:30 p.m. eastern time.
If Obama holds the states polls say are now firmly his, hed have 221 electoral votes, including Californias 55 and New Yorks 29. Romney is considered a safe bet so far for 191 electoral votes, notably Texas 38.
In a close race, other issues could be crucial. Will the unusually rigid Republican stands against abortion and gay marriage help bring conservative Virginia and North Carolina voters to the polls? Or will that also motivate enough opponents to tilt New Hampshire and Colorado to Obama?
Where does immigration fit? Environment? The auto bailout?
With dispatches from McClatchy newspapers around the country, heres a state-by-state look:
North Carolina (15 electoral votes)
Republicans were so certain of carrying the Tar Heel State last time that South Carolina Republican Sen. Lindsey Graham famously boasted: Ill beat (multiple gold medal winner) Michael Phelps in swimming before Barack Obama wins North Carolina.
After Obama improbably carried North Carolina in 2008, the first time since 1976 that a Democratic presidential candidate won the state, Republicans are making no such boasts this time.
This summer, the state has endured a $50 million advertising barrage, with Romney and his allies outspending Obama by more than 2-to-1.
So far, the ad war has barely moved the polls, with most showing the race within the margin of error. But Democrats acknowledge they face an uphill task in a state with the fifth-highest unemployment rate in the country.
Obama is counting on a massive grassroots effort and a boost from the convention that concluded Thursday in Charlotte, and from an influx of new residents from more Democratic-leaning parts of the country.
According to a Gallup survey of ideological leanings of residents in each state, North Carolina was the 22nd most conservative state in the country making it ideologically closer to Wisconsin than to any other Southern state.
With a history of tight elections and a population that resembles the nations, Florida is the ultimate battleground state.
Romney and supporters have dumped an estimated $45 million on television ads in Florida just for the general election. Obama and his allies have spent about $25 million. The Republicans held their convention in the Tampa Bay area, the most hotly contested battleground region of the state.
The two are essentially tied, with Obama narrowly ahead of Romney by an inside-the-error margin lead of about 2 percentage points, according to the averages of the latest reputable statewide polls.
Obama won Florida by fewer than 3 percentage points in 2008, but the toll of the bad economy has hurt his standing. The unemployment rate stands at 8.8 percent, and Floridas foreclosure rate is the third highest in the nation.
Ohio loves its reputation as one of the most unpredictable of the bellwether states, and 2012 is no exception. Obama has visited the Buckeye State 27 times since taking office in 2009, including 11 this year. Romney has been to the state 13 times since last year.
Obama and Romney are locked in a statistical dead heat in Ohio.
The Columbus Dispatch recently recorded its closest presidential poll in modern history, with Romney leading Obama by only 0.22 percentage points, a figure well within the surveys margin of error.
Though Ohio is a Rust Belt state, its doing better on jobs compared with other parts of the country. The states July unemployment rate was 7.2 percent lower than the nations 8.1 percent jobless rate.
Virginia was long regarded as a conservative Southern state. But in 2008, Obama became the first Democratic candidate to carry the commonwealth in 44 years after putting together the broadest state political organization in modern times.
Republicans are fighting hard to get the state back, and Virginia is now among the most volatile of the swing states.
Democrats have made inroads in northern Virginia, where the population has boomed in recent years, particularly with minorities and younger voters. Republicans have electoral strength in the Shenandoah Valley and rural south and southwestern Virginia.
Four years after Obama won Nevada by more than 12 percentage points, this recession-weary state perhaps more than any other tests his argument that the economy has improved on his watch.
Foreclosures are rampant and the unemployment rate still hovers around 12 percent, highest in the nation.
The Republican Party, outnumbered by more than 100,000 active voters in 2008, has reduced the Democratic Partys advantage to fewer than 60,000 active voters this year.
Yet a strong following for Rep. Ron Paul of Texas, evident at the Republican National Convention, and before that at a disorderly state convention, has forced Romney to work around the state party.
New Hampshire (4)
New Hampshire has voted Democratic in four of the last five presidential contests, and Obama won the state soundly in 2008. Romney, who has a summer home in the state and was governor of neighboring Massachusetts, is hoping for a hometown edge.
The Granite States major claim to political fame stems from its first-in-the-nation presidential primary, which provides every candidate with a roadmap of the states political landscape. But its also a tempting prize in the general election, with an electorate so closely divided that its almost always up for grabs.
Young voters and Latinos helped Obama win Colorado by 9 percentage points in 2008, with rapidly changing demographics turning the once reliably Republican state into a tossup.
The states voters are nearly evenly split about one-third each Republican, Democratic and unaffiliated.
Latino voters, who could make up 8 percent or more of the electorate this year, are likely to be critical to the outcome, as are suburban women. Obama did well with Latinos and women voters in 2008, said Kyle Saunders, a political science professor at Colorado State University.
But the unemployment rate remains above 8 percent. Though things are a little bit better off here than in many states, Saunders said, the sputtering economy may still hurt Obama.
Both candidates made treks to Iowa on Friday on the first day after the conventions, a testament to its outsized role in the election.
In between their personal visits, the fight is playing out on the states television screens. Since May 1, the Obama campaign purchased more than $12 million in ad time, according to figures compiled by the National Journal, enormous spending for the relatively small media markets in the state. The Romney campaign has spent less $7.2 million but outside groups affiliated with Republicans have added more than $10 million.
Obama carried Iowa easily in 2008. Farm interests and alternative fuels ethanol subsidies and wind energy remain important issues for the states voters.
Some of Iowas Democrats also have an aggressive anti-war posture that Obama was able to tap.
Romney, though, is relatively popular with the states social and fiscal conservatives, and he favors federal support for ethanol production.
A Democratic presidential candidate hasnt lost Wisconsin since 1984, but that winning streak may offer little comfort to Obama. The Badger State has seen a dramatic political shift recently.
Voters swept Republicans into power in 2010, sending Ron Johnson to the Senate to replace liberal Sen. Russ Feingold, and putting Scott Walker in the governors office.
After Walker curbed union rights in a budget fight, voters sided with Walker again in a recall vote.
Theres been a real shift in government a clear swing in a Republican direction, and you dont even need Paul Ryan on the ticket. But you add him to the ticket and youve got an extra dimension. said Charles Franklin, director of the Marquette Law School Poll.
Romney got a bump in the state when he chose as his running mate the young Ryan, the congressman from Janesville and chairman of the House Budget Committee, pulling within 3 percentage points after trailing by 5.
The state that usually serves as the bellwether for American blue-collar voting will be watched unusually closely this year.
Thought to be a Democratic stronghold, its in play partly because of Romneys family ties and partly because its shown some Republican tendencies.
Michigan elected a conservative Republican governor, Rick Snyder, in 2010. Romney is a Michigan native, from a family still well-regarded in the Detroit area.
His father was the states governor from 1963 to 1969, his mother, Lenore, ran unsuccessfully for the U.S. Senate, and his older brother Scott remains active in state Republican circles.
Mitt Romney faces a big hurdle though: The auto industry is coming back, and Obama is taking credit for the resurgence. Though the bailout program began under President George W. Bush, Obama kept it going strong and his campaign is offering constant reminders of what he did and how Romney opposed the bailout.
