What do you do when...

... there are literally no good candidates running for even one office for which there is a vote? I've thought about possibly voting for the worst, most extreme candidate on the grounds that they would be more easily ousted later. The problem is, how can I justify voting for a pro-death candidate? I could also think about a write-in candidate, but the fact is, if someone isn't on the ballot anywhere, they have very little chance of getting elected.

I had no problem voting for the Constitution Party candidate in the last presidential election, because he was on the ballot in a lot of states, though not CT.

This sort of thing kind of ticks me off, because now my voice can't be heard. I have no good option.
