The problem they have is Trump is the most articulate candidate we have perhaps ever. He has lived in the belly of the beast his entire life and knows what they are going to say before they say it. He will beat them at their own game and has.
Our side has thrown nearly $200 million at him and lost, what can Hillary do?
Hillary or any Dem will be difficult to beat if you see how many electoral votes they start out with. Trump's nationalistic and populist approach does give him a good shot in NV, NH, MI, OH, PA, and FL. He is the only Rep who really has a shot at winning, forget the polls showing Kasich as beating Hillary.
The linkage of immigration and trade issues to jobs will help Trump penetrate traditional Dem constituencies. They cut across partisan lines. And Hillary is a lousy candidate. If the Reps lose in 2016, it is game, set, and match for the USA. The Dems will be the permanent majority party.
