Keep your bitter resentment. I know of some trump supporters who actual did some thing in my precinct and are delegates to the state level. He wont get the 1237 with out people who are willing to do something at the delegate level from inside the party.
Your bitterness is preventing you from doing any real thing to help your candidate. Sorry but the truth is that we have a party system and you need to use what we have to get what needs to be done done.
“Do something” meaning dirty tricks.
The whole political party edifice on both sides is stinking rotten to the core and needs to be burned to the ground.
