If anything should be obvious now, it is that this is not a normal election cycle. You have two candidates who are both extremely unpopular, not just across America but also within their own parties to some degree. Trump is not a normal Republican candidate so applying the standards of what has happened in the previous 4 elections is fraught with increased uncertainty. To some degree, the old saws that the Clintons would apply to normal Establishment Republicans don't readily apply to him. He is more unpredictable, and HRC does not seem to deal so well with unpredictable competition.
it's actually very normal:
1. Most of the states that are ordinarily battle ground states, are still battle ground states. NC, VA, PA, OH, FL, NH, IA, CO.
2. Only a couple of states are potential, new BG states this time around (GA, NV, maybe UT (although I doubt it)), but we say that pretty regularly. NC and VA became BG states in 08 and 12. Before they weren't.
3. The new BG states are there primarily because of demographic changes (large increases in the Hispanic population in both GA and NV). The only real outlier as far as I can see is UT but that's explained by the Mormon population and their apparently visceral reaction to Trump. And again I don't think it actually will end up a BG state.
The Demographic polling follows the last couple of decades:
AAs heavy D
Latinos heavy D
Single women heavy D
White men heavy R
The only differences are that the first three categories are more D fav and the last is more R fav than usual.
The real meaningful difference is that once again the White portion of the vote will drop another 1-2 percentage points. Which means that many more White voters Trump has to find to offset his dismal performance in just about every other demo group.
Hillary is averaging about the same lead that Obama had over Romney give or take...once you take out the extremes on both ends. Not really surprising since she's clearly targeted the Obama coalition and that coalition is a winning one and hates Trump.
You are only right about one thing...Trump isn't normal politician. That's not a positive. A normal politician would have made much more ground up with the bad two weeks Hillary had. A normal politician would be up heading into his own convention, but she's up by around 3 pts. A normal politician would be furiously working at putting together the infrastructure for a ground game in key BG states, would have advertising all over the place in key BG states. A normal politician doesn't say something batcrap crazy/racist/sexist on the reg.
Here's what you will see. Trump may eke out a small overall lead (less than two points) at the end of his convention next week...unless it's a trainwreck.
Hillary will then have her convention, which will be choreographed and well done, and she will get a bump from that. She will probably name her VP during the Republican convention to take some press away from it. That's the incumbent advantage of being able to have your convention second and literally right after the challenging party. any bump is stomped on.
Hillary will be roughly around where she is now, maybe a tick better going into the debates. She will win the debates overall, although like Obama with Romney I could see her struggle dealing with him in the first one.
Then...nothing, we will have a month with no real news, with her up 3-4 points (or more), with the demos remaining what they are.
