No liberal wants to see a conservative in the Oval Office. Not Rubio, not any of the others. But there’s a difference between accepting an ordinary member of the opposition party and accepting a fatuous clown like Donald Trump. The former will enact lots of policies we hate, but that’s democracy for you. We’ve been through it before and we’ll go through it again. The latter is a mockery of everything democracy stands for.

Even if you assume that Marco Rubio might be more technically destructive of liberal policies than Trump—an unlikely but admittedly possible outcome—Trump would be more destructive of the very core of liberalism. If we’re willing to accept bigotry and belligerence and just plain inanity—along with the small but genuine chance of a something truly catastrophic taking place on his watch—just for the sake of maybe getting a slightly better outcome on a few liberal policies, we really ought to just hang it up.

At this point, it’s not clear if Trump can be stopped anytime before November 8th, but liberals should nevertheless be doing everything they can to help his opponents relegate him to the ashcan of history. After all, it’s no sure thing that he’ll lose in November either. There are lots of ways he could win. An economic downturn could do it. Trump’s demagoguery might do it. Some kind of unexpected scandal could do it. Or Hillary Clinton could just run a bad campaign.
