In 2008 and 2012 respectively, neither the McCain nor Romney campaigns were associated with rampant fraud, demagoguery, and indecency. I didn't vote for either of them, but I didn't believe that they were terrible.
The Trump campaign earned a certain image not because it was the Republican ticket but because of its unique properties. There's a price to be paid for that, period. Such as, a lot of communities won't want to have anything to do with it.
