Lots of polls out.

They all say roughly the same thing; after all of the Republicans' efforts in St. Paul, the race is either dead even to perhaps a couple of points for McCain:

The Washington Post (Registered Voters with Leaners):

Obama 47%
McCain 46%

Rasmussen (Likely Voters with Leaners):

McCain 48%
Obama 47%

CNN/Opinion Research:

Obama 48%
McCain 48%

(Their poll of polls suggests McCain has a one point advantage in the race: 47-46.)

CBS News Poll

McCain 46%
Obama 44%

Diageo/Hotline Poll:

Obama-Biden 44%
McCain-Palin 44%
Undecided 10%

So it would seem that the Gallup Daily Tracking Poll is a bit of an outlier, but it generally tracks with the other polls in that it depicts in a rough sense a very narrow race:

McCain 49%
Obama 44%

One thing that the Gallup Poll from yesterday, however, found was that:

The Republican's ties to President Bush remains a vulnerability. In the poll, 63% say they are concerned he would pursue policies too similar to those of the current president. Bush's approval rating is 33%.

I am hoping that is as ominous for the Republicans as it sounds.
