I don't think that any of the other major candidates could have won against Clinton, anyway.
I'd be concern trolling if I said otherwise, kinda like some of the right wingers who go on about how Dems could have had Bernie because he'd be better. It's bullshit.
Repubs made a strategic mistake 8 years ago when they doubled down into the Teahad & obstructionism. They largely held on to the tax & regulatory advantages they'd gained for their wealthy donors but they failed to deliver to their base. They've promised things that they can't or have no intention to deliver. They can't deliver on abortion, for example, no matter how fervently elements in their base want that to be true. But they promise anyway instead of telling people the truth. They have nothing but bootstraps for people like TH & Jasper Texas in general. It's all FUGM, all the time. Don't got yours? Be ashamed, because you're morally inferior. You just weren't smart enough & didn't work hard enough, had de ebil gubmint taking too much of your money to feed the kids of that imaginary welfare queen baby factory somewhere near you. Blame them- don't blame the very nature of capitalism itself & the greed of those at the top.
