There are many delegates running. I did find one declared for Trump. Yes, he could change his mind.
Has anyone polled the candidates for delegate?
The campaigns got people to run for delegate under this system and they know who their people are, if any.
I was asked by the Cruz campaign to be a candidate in my congressional district, but I decided against it.
Contact Trump’s campaign, get on their email list.
I also have a list of candidates but have no idea who they support. I have no idea how to contact the Trump campaign for advice.
