From Eric Dondero:

The Florida Senate race continues to be a nail-biter for conservatives and libertarian Republicans supporting Tea Party favorite Marco Rubio.

From Rasmussen:

The latest Rasmussen Reports telephone survey of Likely Voters in Florida shows Rubio with 38% of the vote and Crist at 33% if Congressman Kendrick Meek is the nominee. Meek earns 21%. Only one percent (1%) prefer some other candidate, and seven percent (7%) are undecided.

If billionaire Jeff Greene is the Democratic candidate, Crist gets 37% support to Rubio’s 36%, with Greene trailing at 20%. two percent (2%) like another candidate, and five percent (5%) are undecided...

the lead in this race has seesawed between Crist and Rubio for months... The race remains a Toss-Up in the Rasmussen Reports Election 2010 Balance of Power summary.

A Rubio victory is critical for Republican hopes of re-gaining the Senate. Without it, the GOP is likely to fall just short 51 to 49. Independent Crist is refusing to state which party he would caucus with if elected.
