BOCA RATON, Fla. (AP) — Vice President Joe Biden didn’t waste any time addressing former Gov. Charlie Crist’s switch from Republican to Democrat at the first of a pair of South Florida campaign stops Monday, where he blamed the GOP for abandoning the middle class.

“Hell, (Crist) didn’t leave the Republican Party. It left him,” Biden told a crowd of about 600 seniors at a Boca Raton retirement community, later saying “one political party in particular has changed so fundamentally that they don’t view things from the same prism.”
