Some folks keep posting the same Rasmussen poll in thread after thread. This outfit is not reliable, so take it with a grain of salt! It was posting a 4 day average which would have the lower numbers from prior to Friday...when Obama showed his biggest gain. Meanwhile Gallup has a 3 days average which would exclude the lower polling done on Obama. The Gallup sample is larger and has a lower margin of error.
Daily Rasmussen Graph shows Obama leading Hillary Clinton on 3/21 45% to 44%. That's the last day of the tracking poll, but the 4 day average is what keeps Clinton in the lead.

Gallup reports:
Barack Obama has quickly made up the deficit he faced with Hillary Clinton earlier this week, with the latest Gallup Poll Daily tracking update on Democratic presidential nomination preferences showing 48% of Democratic voters favoring Obama and 45% Clinton.
Obama fell behind Clinton on March 14 and stayed there until today. "Obama's campaign clearly suffered in recent days from negative press, mostly centering around his association with the controversial Rev. Jeremiah Wright," wrote Gallup analyst Jeff Jones.
"But Obama has now edged back ahead of Clinton due to a strong showing for him in Friday night's polling, perhaps in response to the endorsement he received from well-respected New Mexico Gov. Bill Richardson."
The Gallup tracking poll is based on interviews with 1,264 Democratic or Democrat-leaning voters March 19-21. Its margin of error is +/-3 percentage points.A tracking poll by
Rasmussen Reports has shown a different trajectory. In that poll, Obama clung to leads of 1 to 5 percentage points all week and fell behind Clinton for the first time today, 46%-44%. Rasmussen calculations are based on four nights of polling, compared to Gallup's three.http://blogs.usatoday.com/onpolitics/polls/index.html Rasmussen Reports, whose polls consistently place George Bush's approval rating higher than other polls, published the first poll on impeaching Bush and removing him from office. Rasmussen found that 32% of Americans want President Bush impeached and removed, while 35% want Vice President Dick Cheney impeached and removed.

Rasmussen is increasingly oversampling the dwindling number of "Republicans" in their poll, causing the net support for Bush in the final tally to RISE - even as the real support for Bush among the population falls.
Based on this,
I predict that Rasmussen is going to go down flaming in the next nationwide election, as the built in instability in their polling method finally turns around to bite them in the ass.http://www.dailykos.com/story/2005/11/12/101416/07--------------------
