Most folks don't vote based on policy positions. Likability is still the winner. But just staying away from the more liberal policies some of the candidates are proposing would do it. He's not as scary to them as Clinton was. We just need to shave off a little around the edges to win. Clinton lost PA by about half a percent {45K from a total of 6M votes}. You just need 23K of those to change their vote.
Maybe that's the problem.
Or more to the point; party leaders keep telling us that Americans don't vote on policies because if they did, those same leaders would have to admit their policies don't cut it.
Well, they aren't cutting it- which is why we have who we have in the White House right now.
So maybe it's time to actually focus on policies that matter to the intended constituency? Pandering to the money isn't working anymore...
