Obama up in Quinnipiac

September's Quinnipiac Poll is out, and it's part of the continuing roll out of good news for those of us who yearn for a Democratic presidency:

Obama 49
McCain 45

Their August 19 poll, the one conducted prior to the rollercoaster ride of the conventions had Obama up 47-42, essentially the same spread Obama now enjoys in this poll. This is yet more evidence that the race might be returning to its pre-convention dynamics. The poll observes:

In the matchup, McCain leads 50 - 43 percent among men, compared to 46 - 41 percent August 19, and 52 - 43 percent among white voters, compared to 48 - 40 percent last month. He also leads 71 - 21 percent among white Evangelical Christians, up from 65 - 25 percent.

Obama leads 54 - 40 percent among women, compared to 53 - 39 percent last month, and 93 - 2 percent among black voters. The Democrat leads 57 - 37 percent among voters 18 to 34 years old while McCain inches ahead 49 - 47 percent among voters 35 to 54. Voters over 55 tilt to Obama 47 - 45 percent.
