So, the polling books have been closed on the first half of September, by category, and for your perusal. There were some very interesting polls, also in states rarely, if ever, polled, like Utah, Alabama and California.
D-nomination (national and state), 01-15.09.2015
R-nomination (national and state), 01-15.09.2015
D-vs-R GE matchups (national and state), 01-15.09.2015
Senatorial/Gubernatorial polling, 01-15.09.2015
FAV/UNFAV, APPROVE/DISAPPROVE, other Issues polling, 01-15.09.2015
Lots and lots of numbers, plus graphs and screenshots of what I thought were important internals. Have fun.
