You won't get the chance to bet on it - it is simply the direction in which the US political establishment is careening. By all means, vote your conscience - hell, I'll vote with you - but don't be surprised when that doesn't alter the course much... or even at all.

If anything, it seems like people are more willing to normalize, or at least look away from, atrocities than I would have ever imagined in the past.

Certainly - but then, again... a lot of us always have. That's how we ended up here in the first place, isn't it?
