Idaho billionaire Frank VanderSloot today endorsed Republican Marco Rubio for president and said he plans to raise money for the Florida senator's presidential bid. VanderSloot told the Associated Press he believes Rubio is “the brightest of the bunch."

VanderSloot was one of Mitt Romney’s national finance co-chairs in the 2012 presidential race, raising at least $2 million for the campaign and also donating $1.1 million to a pro-Romney super-PAC. VanderSloot said he and his wife gave $50,000 in June to the Conservative Solutions PAC, which is backing Rubio's campaign.

VanderSloot also has donated $2,700 to Carly Fiorina’s GOP presidential campaign; he told AP reporter Kimberlee Kruesi that Fiorina was a close second, but he decided she lacks Rubio’s charisma. "Marco Rubio has a big edge on Carly Fiorina on the likeability factor," VanderSloot said. "He is just so dang likable." You can read Kruesi’s full report here.
