True, but the sad reality is one of the two of them wins.
But voters don't have to continue supporting them. I can, almost, understand why someone would choose to vote for the "lesser of two evils". But if they elect a candidate who they're acknowledging is evil, to prevent the victory of the greater evil candidate, why would they go on supporting that evil candidate after the election?
I hope I never concede to this logic. But if I do, if I vote for a lesser-evil candidate and they win - the first thing I'll do is organize a campaign to get them impeached.
We've got to stop settling for evil.
