Former Vice President Dick Cheney threw his support to Marco Rubio in the Florida GOP Senate primary Thursday, warning that "Charlie Crist cannot even be trusted to remain a Republican."
The Cheney endorsement represents the most significant national "get" to date for Rubio, and comes as Crist weighs bolting the Republican Party to run as an independent.
In a statement issued by Rubio's campaign, the former vice president urged Crist to stay in the primary or drop out of the race altogether. "The only winners from an independent bid by Crist would be Barack Obama and Harry Reid," Cheney said.
Crist's plunging poll numbers and open consideration of an independent run have prompted a stampede of previously neutral GOP figures to get behind Rubio. In less than a week, the former state House speaker has won support from 2008 presidential candidate Mitt Romney, House Minority Whip Eric Cantor and now Cheney.
