WASHINGTON - A few weeks into her first term in Congress, Michele Bachmann stood around a radio booth as a news reporter described her as an evangelical Christian who had the potential to be "very outspoken" on social issues.
Bachmann approached moments later to inform him, "I'm also a tax attorney."
As the Minnesota Republican rises to prominence in the national Tea Party that meets this weekend in Nashville, the two sides of Bachmann's political persona have been fused into a mirror image of the newly charged conservative reaction against government spending and much of the rest of President Obama's domestic agenda.
But Bachmann's 11th-hour decision to bow out of the Tea Party's first national convention -- citing concerns about its for-profit model -- also reveals the fault line between the Republican hierarchy and the Tea Party's rank-and-file.
Bachmann was one of the few elected officials invited to this anti-establishment, small-government gathering. Her absence leaves the stage to kindred spirit Sarah Palin, the former Alaska governor who electrified down-home conservatives as the GOP's nominee for vice president in 2008.
But as an officeholder seeking reelection, Bachmann is one of the more pivotal leaders in the movement, a bridge between grass-roots Tea Party activists and a Republican Party debating whether to tack to the right or the political center.
It was Bachmann's name that was chanted by thousands of Tea Party protesters who rallied to her "emergency House call" last November on the steps of the U.S. Capitol.
GOP colleagues who once sought to muzzle the Minnesota Republican for inflammatory remarks on TV -- she once suggested that Obama and fellow lawmakers were un-American -- have been forced to re-evaluate her as the envoy of a populist movement born in church basements, at race tracks and gun shows across the country.
