If you can't imagine pulling the lever for Trump I get it. I'm not sure I can do it either. If you are an elected GOPer and say the same, I can live with that.
If you are an elected Republican office holder and claim you will not only not vote for Trump but will vote for Hillary then you have betrayed the voters, the donors, and the party. You should return any re-election funding you got from the GOP. You should be booted from committees. You are no longer part of the Party. In fact you are proven to be untrustworthy, a liar, and opportunist.
You fit in well with Hillary Clinton.
No wonder people rank politicians right up there with dog shit in popularity.
