How to poll dance

Look at what the Washington Times tries to sell today:

After three nights of nonstop testimonials to Monsieur Kerry's charisma, the Rasmussen presidential tracking poll shows him with the same three-point edge — 48 percent to 45 percent — he had when the first delegates trickled into Boston. A Washington Post-CBS News poll earlier in the week showed the president with a two-point lead.

They must have purposely ignored the warning at the Rassmussen site:

Today's results are based upon survey interviews conducted Tuesday, Wednesday, and Thursday nights. Only a small portion of the interviews were conducted following Kerry's speech. Monday's update will be the first based entirely upon interviews conducted following the speech.

Normally I just ignore the Washington Times altogether. But this one I couldn't let slip.
