No, this should encourage the Trump voters to go and vote. If he gets 50% then he gets the nomination no questions asked.
Trump supporters needs to stop whining and go out there and try to get their man to 50%.
If I were a Trump supporter that’s what I’d do, instead of worrying about it being “stolen”.
You almost sound like you don’t really think Trump can get to 50%, and want to pre-emptively argue that he should get the nomination even if he falls short because he has the plurality.
Also, I personally saw to it that every member of my extended family got to the polls and voted. 100%. I've done my voting part until November now.
