To all the dips[Inks]ts in this thread, tell me the difference:
I'll have a go
Romney was at 46-48 in all the 2012 polls, Trump is at 41-44 in all the 2016 ones. The difference between Clinton+12 and Trump +1 is really just Clinton's number. And Trump seems stuck in an unenviable position.
The second thing you can take from that is the continued strength of third-party polling this late in the game, which wasn't there in 2012. Will it hold up in two weeks time? Will it revert to Trump as NeverTrumpers crack, will it stick or will it flock to Hillary as some of the other polls suggest it might?
