I agree, but I wish there were some way to ensure that voters were making an informed choice.
In the case of Bobby Sands, I assume they were. That was a high profile case. It’s even vaguely possible to make the case that he was a political prisoner.
But, almost daily I see interviews with Trump voters who seem to have lost their connection with reality. And, it’s not even a wrong but consistent worldview. It’s just a bunch of incoherent conspiracy theories that fall apart under the most gentle questioning. Unfortunately, there’s probably no way to restrict voting to only sane and well informed voters, because any restriction you put in place could be abused.
In a first-past-the-post system, an independent only ends up stealing votes from the mainstream candidate that’s closest to their position. He’d undermine the Democratic candidate, making a Republican win more likely. He’s smart enough not to want to do that.
