The red states are again going to vote red. If they voted for Robber Baron Romney last time they will vote for Trump The Chump this time too.
The blue states are again going to vote blue. Voting for Hillary is like giving BHO a 3rd term. Same syndrome as with Reagan/Bush back in 2008. Whenever a POTUS is really popular then his VP is easily elected. In this case Hillary as the Sec State is the next best person. Biden is too old to run.
The SWING STATES are the ones where the polling matters.
Overall polls are meaningless.
There was one state poll that I saw that should really have Trump worried. I did not check the poll's methodology, so it may have some flaws, but it showed Hillary up by 14 points in Iowa. The poll was conducted by Loras College, so I have no idea what their history is. If this poll is remotely close to being accurate, Donnie has a big problem, because if Hillary wins Iowa by 14, Donnie is in trouble in a whole lot of other states.
