TAMPA, Fla. (AP) — Republican presidential candidate Mitt Romney says he's "ready to lead this party and our nation."

Romney won yesterday's Florida GOP primary, taking 46 percent of the vote. Newt Gingrich got 32 percent, Rick Santorum 13 percent and Ron Paul 7 percent.

Gingrich lost to Romney by a wide margin, but he's promising to stay in the race, saying, "We are going to contest everyplace."

Gingrich plans stops in three Nevada cities today. Romney plans to campaign in Nevada and Minnesota. Nevada and Maine have caucuses on Feb. 4. Minnesota, Colorado and Missouri all hold contests three days later.

Romney has the lead in the number of delegates. Last night's Florida win gives him 50 more, with a total of 76 delegates to the Republican National Convention. Gingrich has 26, Santorum has 14 and Paul has four, but 1,144 are needed to clinch the nomination.
