Funny. A lot of people thought the Club for Growth had endorsed Marco Rubio.They had not . . . at least until today.It is now certain that Charlie Crist will get a run for his money in Florida. The Club for Growth is today announcing its endorsement of Marco Rubio in the Florida Senate race.They’ll bundle a lot of money for Marco making this an extremely competitive primary. Charlie Crist’s no good, rotten, very awful week just keeps getting worse.“The Club for Growth PAC has spent months studying this race, and we have concluded that either Charlie Crist or Marco Rubio would be heavily favored to win next November against likely Democratic nominee Kendrick Meek,” Chris Chocola, President of the Club for Growth, said. “The only question now is what kind of Republican will Florida send to Washington next year: a pro-growth Republican with a record of fiscal conservatism or a big-government Republican with a record of tax increases?”Nice.
