Dr. Pepper, I think you are taking politics a little too seriously. I really cannot imagine being spoken to about American politics in heaven.
While you want to make an informed vote, investing that much emotion, to the extent of demanding תשובה for voting for the other party, is a real waste of human resources.
Those of us who vote Conservative have our reasons, economical, social and global. Those who vote Democrat have reasons as well. They view Republican behavior as irresponsible, uncaring, and dangerous. Both sides have weighed the options, are affected by prejudice, look away from some things in favor of others. It is clearly not out of malice.
