Or they made what they thought was the best choice among the only two viable choices.
The biggest problem in the US, maybe the world, is that we don't have instant run-off voting to allow competition in federal gov't. We're trapped by this one oversight of the Founding Fathers.

This is a wrong methodology. If you don't accept them - don't make such choice at all. There were other alternatives, but the current voting system prevents anything from competing with the two dominant parties.
I disagree. Making "best choice" you endorse the wrong one. If you didn't like it, you could vote for alternative candidates which you preferred, even though the logic dictates that they had low chances to win.
