Define “Trumpster.”
I guess it would be those who have supported Trump since, say, before Wisconsin. It was not meant as a pejorative in the sentence.
To go back to the original topic, I don't think that a Gov. Trump in 2004 would have done any more to keep Terri alive than Gov. Bush did. That isn't enough to keep me from voting for Trump in Nov., for there are many reasons that Jeb! would have made a horrible President, most of which are not true of The Donald.
