I don’t know if the quote is real or not, but it’s highly unlikely. Bundy began killing outside Florida, at a time when the death penalty had been ruled unconstitutional. He also briefly accepted and then turned down a plea bargain that would have resulted in a 75 year sentence, so it doesn’t appear his plan was to have himself executed.
Beyond that, Florida is certainly not the best state to go to be executed. Texas has executed four times as many prisoners since the death penalty was reinstated in 1976, as have a couple of other states. In terms of “efficiency” - the ratio of executions to current death row inmates - we’d be near last (having the second largest number of current death row inmates). Virginia appears to be the “most efficient” DP state.
If by “bleeding hearts” you mean the US Supreme Court, yes.
