It won't take a white man to defeat Trump, so let's just stop pushing the notion that gender or race should factor in who is the nominee. Warren could easily defeat Trump, because she is progressive, but still pragmatic enough to win over swing voters. Besides that, Trump won by about 70k votes across three states to secure 270 and lost the popular vote by millions, so he's far from being in a position of being that secure against credible candidates.
Aren't you contradicting yourself in that sentence? 
My point wasn't that a white man can't defeat Trump, it's just that race or gender shouldn't be the predominant factor in selecting a nominee. There are other people besides white male candidates that could be viable, you know.
