Because they are stupid for voting for a right wing candidate. He's going to turn on them immediately and destroy their livelihoods because that's what they do. That's all the right wing ever does and has ever done. They're not here to help you. They're here to help themselves, usually to the fruits of your labour. And then they call us thieves for demanding our cut of the wealth back. The right wing is just organized crime with better PR, that's all they've ever been and that's all they'll ever be. Oh they'll dress it up in a song and dance about some nostalgic nonsense or another, it's all a spectacle to keep you distracted while they pick your pocket. "Oh we're the party of law and order" bullshit. They'll complain about crime, loudly and for hours to anyone who will listen, but their "solutions" are usually just more ways to profiteer off of it while pretending their useless gestures are "Doing something."
At least they're more honest about it than the damned centrists, but given the choice of being stabbed in the back or in the face, I'd say I'd rather not be stabbed at all.
