TAMPA, Fla. (AP) - The tea party has made a solid imprint on its first GOP presidential convention, from the speeches to the platform to the displays of deep opposition to President Barack Obama. With this backdrop, Mitt Romney - who is hardly the first choice of this group of insurgents - will accept the nomination Thursday.

Romney needs the tea party's vigor to ensure the GOP's conservative base is fired up and works on his behalf this fall. The three-year-old tea party movement needs the Republican Party and its new standard-bearer to champion its causes and get its agenda enacted.

The two sides have never had much affinity for each other, but the tea party loved the choice of Wisconsin Rep. Paul Ryan as Romney's running mate.
