That's not what happened, you're giving him far too much credit. He became a weed spokesperson. He's a fucking hypocrite. He was "vehemently opposed to Marijuana legalization" during his time in the house, got paid $20m, dropped out of congress, and became a lobbyist for a cannabis investment group. He's a fucking twat.
