I think the Democrats would be in far better shape in 2020 after four years of Trump or Cruz, honestly; they'd likely be united behind a progressive candidate for once.
Oh sure, they would. The rest of us would be
fucked, though, because Cruz would probably start the Third World War and Trump would drive our economy so far into the ground, we'd be closer to post-WWI Germany than is comfortable. I'm not sure about you, but I'm not fond of economic ruin. You saw how bad shit got under Bush, and he was just a fucking idiot, someone as actively malevolent as Trump or Cruz would probably kill what little recovery we've fucking gotten and, I'm sorry, but I'm really super uncomfortable with the idea of sacrificing all the social and economic progress we
have made on
a tantrum the slim chance that such a state wouldn't drag the Democratic Party even
further to the right, which is a distinct possibility.
But, go ahead, flip that coin. I'll do whatever I can to keep your childish ass from opening Pandora's Box and killing us all.
