The Hill's Justin Sink reports that the George Harrison of tracking polls, Reuters-Ipsos, hasn't detected any movement yet.
President Obama isn't seeing a bounce in the polls after the first two nights of the Democratic National Convention, a promising sign for Republicans worried that this week's proceedings could erode the marginal national lead built by Mitt Romney following the GOP gathering in Tampa, Fla.
The Reuters-Ipsos daily tracking poll found Romney with a 45-44 percent lead over Obama, just 1 percent less than on Wednesday.
By contrast, Romney had seen a 6-point gain in his favor in the same poll on Thursday since the Republican convention the preceding weekend.
"We're not seeing a sort of glimmer, at this point, of a bump," Ipsos pollster Julia Clark told the wire service.
There are some serious caveats to the survey results. The tracking poll measures responses over a five-day period, meaning that responses from three of the poll's five days came before the Democratic convention began. And the poll was conducted online, which is generally seen as less reliable than telephone surveys.
Let's see if anything shows up today in the more visible, Lennon and McCartney tracking polls -- Gallup and Rasmussen.
