Calling it a "difficult, personal decision" and saying that he had been encouraged by hundreds of people to run, Mississippi Gov. Haley Barbour just announced that he will not be a candidate for the GOP presidential nomination in 2012.
"A candidate for president today is embracing a 10-year commitment to an all-consuming effort, to the virtual exclusion of all else," Barbour added in a statment. "His (or her) supporters expect and deserve no less than absolute fire in the belly from their candidate. I cannot offer that with certainty, and total certainty is required."
