Jonathan Karl over at ABC News threw some cold water on Florida Republican U.S. Sen. Marco Rubios prospects of ending up as Mitt Romneys running mate. Karl is reporting that Rubio has not yet been vetted by the Romney camp.

Knowledgeable Republican sources tell me that Rubio is not being vetted by Mitt Romneys vice presidential search team. He has not been asked to complete any questionnaires or been asked to turn over any financial documents typically required of potential vice presidential candidates, Karl wrote.

Looking to topple a fellow congressional Republican -- U.S. Rep. John Mica -- in one of the most closely watched primaries in the nation, U.S. Rep. Sandy Adams took aim at the immigration policy that President Barack Obama unveiled on Friday.

U.S. Rep. John Mica, R-Fl, is facing one of the most intriguing primary contests in the nation when takes on U.S. Rep. Sandy Adams, R-Fl, in August.

?Adams is looking to position herself to Mica's right--but he shows no signs of making it easy for her. Mica looked to score points with conservatives on Monday as he came out swinging against the immigration reforms announced by President Barack Obama last week.

Former Senate President Tom Lee continues to gain the backing of the Republican leadership for his return to Tallahassee. While Lee faces Rep. Rachel Burgin, R-Tampa, in the Republican primary for a state Senate seat, a host of prominent GOP leaders continue to endorse him. On Monday, state CFO Jeff Atwater, who served as Senate president himself before running for his current post in 2010, announced that he was backing Lee.

Republican congressional hopeful Ron DeSantis, running in a new district stretching from outside of Jacksonville south to Volusia County, won the support of prominent national conservative leaderPhyllis Schlafly and the Eagle Forum PAC on Monday.

While Mitt Romney has won enough delegates in the primaries and caucuses to claim the Republican presidential nomination, Ron Paul continues to pick up delegates for when the GOP holds its convention in Tampa come August.

Paul picked up 21 out of 25 delegates up for grabs at conventions in Iowa over the weekend. Rick Santorum, who nosed out Romney to win more popular votes than any of the other candidates in Iowa, pulled out of the race earlier in the election cycle.

Former U.S. Sen. Rick Santorum, who broke out of the second tier of Republican presidential candidates to win more than 10 state contests earlier in the year, shows no signs of heading to the political sidelines.

Last week, Santorum announced that he was forming a new political organization called Patriot Voices and, on Friday, he waded into one of the most competitive Republican primaries in the nation.

With two months to go until the Republican primary, U.S. Rep. Connie Mack continues to ignore his rivals to focus on Democrat incumbent U.S. Sen. Bill Nelson.

The Mack team sent out an email to supporters on Friday that hammers Nelson but ignores the other Republicans in the race.

Former Gov. Mike Huckabee of Arkansas, who has since moved to the Sunshine State, offered kind words for Max Page -- the little boy who made a memorable appearance in a Volkswagen commercial -- in an email to supporters sent out on Thursday.

With Sen. Jim Norman, R-Tampa, ending his bid for re-election earlier in the week, House Speaker Pro Tempore John Legg, R-New Port Richey, has been garnering endorsements in the race to represent parts of Pasco and Hillsborough counties in the Senate.

After reeling in the support of many of the leaders of the Senate on Thursday, Legg garnered the backing of the Florida Medical Associations (FMA) PAC on Friday.
