Five years ago, Ron Paul’s popularity was still surprising. Sometime in 2007, the former physician, longtime crank in Congress, and thoroughly fringe Republican had somehow turned his shtick into success — at least monetarily. Paul raised more than $31 million in the 2008 Republican primary even though he never actually won a contest where actual delegates were at stake. For a longshot like Paul, it wasn’t the chance of his success that drove people to donate; on the contrary, all but the deluded knew he would fail.
