What are the issues?

Well, to check that out, let's look at some polls, shall we?

According to Gallup ( Feb 2015 ) The top three were Government, The Economy, and Unemployment

ABC news ( Mar 2015 )  Listed 15 of top worries.  Amongst the top three: Healthcare, The Economy, and Terrorism.  A considerable number cited the size and scope of the government.

A more recent poll  ABC/WAPO ( Nov 16-19) poll:  Economy, Terrorism, Healthcare with Immigration not far behind.

Actually, Immigration and Terrorism are really the same thing.  If the terrorists can't get in, they can't do any terrorism.  If you control the borders, they can't get in.

The trouble with the GOP is that they think that cutting taxes is going to make the Economy roar.  Nope, don't think so, and I consider myself a pretty strong conservative. They should forget about that, as taxes are not high priority right now.

Some Democrats are obsessed with taxes as well.  They think taxes should be higher.

Trump has got it right on Immigration and maybe Terrorism too because the two are related.  So, why all the opposition?  The powers-that-be want unlimited immigration, but that only leads to Terrorism.  Trump is challenging them and he is likely to win, or he will bring the house down for the GOP.

Trump's ideas on the Economy is to get "better deals" on trade.  Well, I don't know.  I suspect that the deals we get aren't very good, but it won't matter all that much if we were more competitive.  You can't polish a turd.  It's easy to understand how Trump thinks, but it is disappointing that he doesn't push things like clean coal and molten-salt reactors as a way towards a competitive advantage in trade.

Unemployment is just the Economy, so those two can be merged.

Size and Scope of Government?  There's not a whole lot to go on with Trump on this one.  I need to research it.
