@thomasfuchs I'd go further and say THE START of Democracy is about electing the best person. You have to keep engaged after that and be aware of issues, contact your representatives, protest and otherwise bring pressure to bear, etc.
And THAT should inform who you vote for. Like you say, there's no perfect candidate, so ultimately you're trying to select the best OPPONENT to have for the next four years. Who do you have the best chance of winning the important fights against?
