Former State Treasurer Richard Moore has decided not to seek the Democratic nomination for governor, as the primary field began to firm up in the wake of Gov. Bev Perdue's announcement that she would not seek re-election.

“I have decided not to be a candidate for Governor in 2012, and look forward to supporting our nominee,” Moore said.

“I want to thank everyone who encouraged me to run this year, and also express my gratitude to all North Carolinians for the privilege of serving them in the past.''

Moore had the potential to shake up the field because of his political experience and because of his ability to self-finance his campaign. He unsuccessfully sought the Democratic nomination for governor in 2008.
