Crist supporters launch anti-Rubio site

Florida Gov. Charlie Crist's (R) supporters are apparently no longer content to sit back and watch Marco Rubio narrow the gap in their Senate primary.

They have gone up with a website, TruthAboutRubio.com, looking to put a dent in Rubio's sterling reputation among Republicans (44 percent positive, 3 percent negative in one recent poll). Rubio has come within 15 points of Crist in a recent poll after trailing big early on.

It's an acknowledgement of Rubio's traction, for sure, but also proof that Crist's supporters aren't going to take this primary sitting down.
