Frank Roche, a Cary stock trader and talk show host, plans to challenge Renee Ellmers in next May's GOP primary in the 2nd Congressional District.
Roche has scheduled "a digital town hall'' for Oct. 23 to talk about debt, deficits, immigration, the Affordable Care Act and the 2014 race.
He is soliciting volunteers to challenge Ellmers, a two-term congresswoman from Dunn.
"If you're a self-starter, have a passion for politics, or are concerned and frustrated by RINO's or faux conservatives in DC, come get involved,'' Roche wrote in an email to potential supporters.
Roche unsuccessfully sought the GOP nomination for state treasurer in 2012 and the 4th District GOP nomination in 2010.
Also considering a challenge against Ellmers is Jim Duncan, chairman of the Chatham County Republican Party.
Although she owns one of the most conservative voting records in the House, Ellmers has come under fire from the tea party faction of the party because she was slow to support a government shutdown as a tactic to defund the president's health care program -- a move she eventually voted for.
