How does TRUMP possibly win?

[Frodo]

He doesn't.  The end.

Like he didn't have a chance to win the nomination?

Yes, because the voters deciding the general election are going to be exactly like the GOP primary electorate.   

Stop comparing apples to oranges.

What has to happen in order for Trump to become president?

I just don't see Trump winning. His absolute ceiling is a 2% loss. He has completely alienated minorities and educated, upscale whites. If we assume that he gets 10% of blacks and 20% of Hispanics/Asians, he will need 66% of the white vote (the percentage Reagan got in 1984) in order to barely win.

I know people say things like "There is still 6 months until the election. Anything could happen."

The polls were actually pretty accurate 6 months before the 2012 and 2008 elections.http://www.realclearpolitics.com/epolls/2012/president/obama_vs_romney_compared_to_obama_vs_mccain.html

I just can't see us electing a joke candidate like Trump. Trump has a 0.000001% chance of victory.

"Educated, upscale" whites can be racist too.
