Not to rehash the past, but I thought we had gotten it clear by now: voting for the guy does not indicate support. Americans vote for the candidate they fear and despise the least.
If you voted for Trump, you supported Trump. It's OK to change your mind, but people need to own and take responsibility for what they do at the ballot box.
That's exactly the flawed logic that is keeping us in this two party system. If we just vote for the candidate we support, neither Trump not Hillary would stand a chance.
The trouble with convincing people to actually do that is that most Americans feel the need to be on the winning side. "My vote is worthless unless it's for someone who can actually win."
