I'm hoping Trump's surge in the polls will make the reluctant Republicans realize that telling the truth will make people like you more than being politically correct. THEN we might see a real campaign based on honesty and candor.
I just re-watched the entire speech. He COULD win he IS saying the right things. NOT the PC things but the right things.
The far right things. Candidates don't win by alienating half of their voters.
So far he's managed to appeal to hard core Republican voters who would vote Republican no matter what. He hasn't appealed to voters who could vote either way, or potentially democratic voters who might change vote.
Hispanics don't really vote Republican, they're an easy target. However 30% of Hispanic voters (more or less) voted Republican in 2012 and 2008. More in when Bush won, he had 35% and 40%. So for a Republican to win they're looking at getting more of the Hispanic vote than McCain or Romney.
But Trump isn't going to get much at all.
