From Rasmussen Reports:
Former state House Speaker Marco Rubio continues to lengthen his lead over Governor Charlie Crist in the contest for Florida's Republican Senate nomination. A new Rasmussen Reports telephone survey of likely Republican Primary voters finds Rubio leading Crist by 18 points, 54% to 36%. Four percent (4%) prefer some other candidate, and seven percent are undecided. Those figures reflect a five point increase in support for Rubio compared to a month ago. Support for Crist has changed little over the past month. In December, the two GOP hopefuls were tied at 43% apiece. The new findings mark Rubio's best showing to date and Crist's worst...
Rubio now carries male GOP voters by a two-to-one margin but breaks even with Crist among women. The governor also breaks even among moderate Republicans, but conservatives in the party favor his challenger now by more than 40 points. It's telling that Florida Republican Primary voters are now evenly divided over Crist's performance as governor. Forty-eight percent (48%) approve of the job he is doing, down eight points from January, but 49% don't approve. Those numbers included eight percent (8%) who strongly approve of how Crist is governing and 20% who strongly disapprove. Keep in mind that those figures are among Primary Voters in the Governor's own political party. Fifty-four percent (54%) of likely primary voters have a favorable view of Crist. This marks an eight-point drop from the previous survey. Sixteen percent (16%) now view him very favorably. Forty-four percent (44%) of Republican voters in the state now have an unfavorable view of the incumbent GOP governor, including 14% whose view is very unfavorable. Only two percent (2%) have no opinion of him.
By comparison, favorables for Rubio total 67% percent, including 34% who have a very favorable opinion of the Cuban-American politician. Only 15% view him unfavorably, including four percent (4%) with a very unfavorable opinion. But 18% still don't know enough about him to have an opinion one way or the other.
