I thought I should write up today's Rasmussen poll since yesterday's showed Obama losing a point and folks were worried the bounce wouldn't last. But he's actually holding steady at 6 points, attracting 47% of the vote and John McCain gets 41%. With "leaners" Obama hits 50% and still leads by 6%.
In the Rasmussen weekly tracking poll listing of 2004, which you can check out here, you'll see that John Kerry never had a lead of 6 points. His biggest lead was 2.8 points, in August. Most of the time he was behind or led by much less than that. Like 1.4 or even .6. George Bush also never had a lead of six points. So ignore the Dukakis comparison--that poll was probably an outlier. When we compare where Obama is now to where Kerry was in 2004, he is in a markedly stronger position.
When Hillary and Bill Clinton start campaigning for Barack and when he starts advertising on television, I expect he will increase this lead somewhat.
Also, check out fivethirtyeight.com for the slew of polls that came out today and yesterday, all showing Barack consolidating Democratic support.
