What he said. Rasmussen and Gallup are much better indicators. I watch this stuff everyday, and the most skewed polls so far have been Zogby and the USA Today/Gallup polls. Hotline/FD (usually skewed towards Obama) is pretty unreliable too. This is what I mean. There is about a 10-point difference on average. That is too much to show that there aren't some serious problems with the polling method. It isn't within one of those other polls margin of error:

Congrats on finding one time in July when they were way off.
I just went through the polls for the last several months, and the USA Today/Gallup poll is not as far off as you would suggest in the vast majority of cases, and in many cases they had Obama higher than other polls, you found one instance to suit your argument.
Is it not significant that on Tuesday of last week, USA Today/Gallup had Obama up by 7, but as now, the same poll has McCain up by 10? That's a 17 point swing on the same poll within just a few days. I generally am not a fan of polls, but I saw a 17 point swing as somewhat significant.
Here's the data from the last round, they were pretty close then. Looks like CNN was way off, though.
| CNN | 08/29 - 08/31 | 927 RV | 49 | 48 | Obama +1 |
| Hotline/FD | 08/29 - 08/31 | 805 RV | 48 | 39 | Obama +9 |
| CBS News | 08/29 - 08/31 | 781 RV | 48 | 40 | Obama +8 |
| USAT/Gallup Tracking* | 08/30 - 08/31 | 1835 LV | 50 | 43 | Obama +7 |
