Quote from Ripley:
What these polls are not taking into account is which of those polled will be excited to actually go and vote. Republican base is much more excited than the democratic base, and you cannot take that into account in a poll.

Democratic Enthusiasm Swells in the Swing States, Nationally
Voter enthusiasm in these states has grown among members of both political parties; however, Democrats' level has increased more. Thus, whereas equal percentages of Democrats and Republicans were enthusiastic in June, Democrats are now significantly more enthusiastic than Republicans, 73% vs. 64%.
Gallup finds a similar pattern among voters nationwide. Overall, 55% of U.S. registered voters in the latest poll are either extremely or very enthusiastic about voting in this fall's election, up from 43% in June. This includes a 19-percentage-point increase among Democrats and roughly 10-point increases among independents and Republicans.

My mistake it was only 2 - 1.Quote from AK Forty Seven:
3-1 vote about what ?
Quote from Lucrum:
Not here in ATL they haven't as demonstrated by a recent 3 - 1 vote that the polls indicated was going to be close.
