They suck, no doubt about it, but fascists suck way, way more. “Vote blue no matter who” is effectively what you have to do in a two-party system, but in reality not voting red is what’s important. And yes, “Vote for the guys who are less bad” is a terrible message and contributes to the fascists winning. But voting is vital (even now, if only at a more local level), and not voting for fascists is extremely important.

Voting for whoever will cause the least harm to the country is the right thing to do. “I won’t vote for the lesser evil!” does not accomplish this and actually goes in the opposite direction. But people are emotional and not practical beings overall, so the guys who are better at appealing to emotions win and we all suffer for it.
