By endorsing Charlie Crist for the Senate, the NRSC is getting involved in Florida’s GOP primary more than 15 months before it will actually take place (August 24, 2010). It’s also selecting a very liberal Republican (Crist supported the Obama “stimulus”) against Marco Rubio, a considerably more conservative choice who is also a credible statewide candidate. Is Crist more electable than Rubio? Arguably. Is Rubio nevertheless capable of winning a general election next year? Certainly. This is a contest that the NRSC should sit out, as Florida Republicans decide for themselves what to do. Instead of trying to beat conservatives, the NRSC should save its resources for defeating Democrats.
