The candidacy of Donald Trump is both a blessing and a curse for those who view it as a way to tarnish Republicans. Trump is a literal gaffe mine who cannot be taken seriously but Americans as a whole are easily swayed by celebrity candidacies (Arnold Schwarzenegger as Governor of California). It is possible to seeing him win the presidency although more likely he'll flameout and pull a Perot (I'm out of the race, Larry!).
I watched his NBC News interview and I dislike Trump in every way not viscerally but more in the way you dislike the villain roles in professional wrestling who boost themselves with phony boasts and trash talk. Wrestling is a good analogy as the way Trump slapped around the interviewer also reminded me of the WWF.
But one can see how people could like Trump. He speaks very directly and is filled with confidence and is unafraid to go after his opponents. On at least two issues he comes off as sane - Stating he was opposed to the Iraq War and only kept quiet about it after President Bush told him to and his opposition to bad trade deals that hurt American workers.
It is also funny to see Republicans support a man who not that long ago supported gun control, universal healthcare, and gay marriage.
Trump is a jackass and a buffoon and Everything he says is a joke- For example about what successful business man he is but has declared bankruptcy and lies about his net worth. His personal life I imagine is full of skeletons. He is offensive and deliberately so in speech but Democrats should net get too excited - Trump could win.
Be careful about what you wish for it might come true.
