@McGentrix,
My only suspicion about Trump supporters, in this context, is that a substantial chunk of them might be disaffected independents with a history of non-participation in the formal political system in general, and particularly at the level of state party primaries which do not even decide elections but only nominees (or more accurately, state delegates who are then obligated to vote for a particular candidate at a nomination caucus).
If I were such an individual, I might have only the foggiest grasp of electoral politics, imagining that the nomination process occurs as the result of some vague machinations that reflect each candidate's poll numbers, is determined by a few party die-hards who are bound to vote for the most popular candidate, and that my vote is only needed for the presidential general election. I might not be registered to vote, or understand that the arcane process required for me to be qualified to vote in a state party primary might mean jumping through some bureaucratic hoops ahead of time, and not just driving downtown and waltzing in on election day.
In any case, I might look at Trump's landslide lead in the polls, and decide that he didn't need my personal help and that I needn't interrupt my dinner or television viewing to carry out a time consuming chore that wouldn't change the outcome because my candidate is a shoe-in anyway.
