The polls are wrong because Trump voters are "afraid" to say they will vote for Trump when contacted anonymously over the phone by polling firms, even Republican-sponsored ones like Rasmussen....

In other words, have you thought that polling companies ask certain people certain questions?
BTW, you know that your two points aren't actually mutually exclusive, right?
