Which part were you angry about? That they changed, or that they couldn't vote as a result?
I am an independent 3 years out of every 4. In presidential election years, I re-register as a Republican. I re-registered last year so that I'd make the Caucus deadline. It's a complicated mess, for sure.
You are not alone on that
I guess I was more angry with myself for not disussing the primary with them. I figured they have been registered republicans their whiole life for sure they would be voting. I found out the day before when I called them to see who they were going to through their vote behind. I was bummed.
I thought about re-registering as an independent when Lou Dobbs was pushing it but I figured it would be a bad move because I lived in a closed primary state.
In closed primary states the independents have no choice but to accept whoever the nominees are. In our two party system it seems like being an independent actually helps the establishments in Washington.
