You do need a certain percentage of Low-Info Voters to win elections.
Guys like Romney get zilch of that vote.
Trump is the anti-Romney. If Trump was hit with that 47% attack he would have attacked backed. He would have turned it around on them by making it about the working 53% who have to carry the 47% on their backs.
AS for the Candy Crowley trick—Trump would let her have it with both barrels. Such as —Where did that paper come from? Is there collusion between you and the Obama team?
Trump may not be perfect but he has what it takes to win elections. I think he will be more conservative than not and will bring the nation in a general conservative direction while adding many blue collar Democrats to the party. These are the working people who are working hard for their money while having less and less to show for it.
