This guy sounds a tad unsavory. And, yes, I can understand why Democrats would want to primary a Democrat who flat-out endorses the GOP Presidential Candidate, whomever that is.
But I wonder if Vernon Jones is more effective on behalf of his constituents than other Democratic state legislators in Georgia, if for no other reason but that he sides with the GOP on at least some key issues. There is something to be said for that if it's the case.
Doubtful, my understanding is he's always been regarded as a gadfly.
