Evangelicals come with serial numbers now?
I mean, how long do you expect people to participate in a game where there is no way to change the outcome for the better? People can act stupid, but that doesn't mean they are stupid - more and more people are starting to see how this spectacle that the political racketeers and their media cronies insist on calling "Democracy!" really works. If you expect people to just bounce back from such realizations and simply "vote strategically" you're in for disappointment.
I'm not USian... but if I was, would I go vote with you? Sure. But that's only because I've had a long time to digest the fact that my vote means absolutely nothing (so-called "representative democracy" is a racket everywhere - not just the US), and would only do it out of solidarity with all the people who are terrified of what is coming next.
I've seen the ways that people have tried to get out the vote for this year's election in the US.. and I'm afraid to report that, so far, it's not working - and that's not your fault..
