Much has been made about how Sen. Barack Obama appears to have weathered nationally the storm over the controversy about the Rev. Jeremiah Wright. While Obama is in a statistical tie with Sen. Hillary Clinton in the latest Rasmussen daily tracking poll, Gallup has him up by eight points.

But Democrats worried that Jeremiah Wright will hurt Obama with "lunch-bucket" working class voters in bellweather states or that the party infighting will hurt their nominee have to be troubled by the latest Rasmussen poll in the Show-Me State.

For Obama, the results mirror a previous Survey USA poll and they show Claire McCaskill's going to have a hard time making good on her pledge to deliver Missouri for Obama. But Clinton supporters shouldn't crow just yet. Unlike last week's Survey USA poll, the numbers in Missouri aren't good for Clinton either although she does fare better than Obama.

Rasmussen finds Republican presumptive nominee John McCain has opened up a significant lead over both Obama and Clinton in Missouri and now places the Show-Me State in the "leans Republican" column. (And as Missouri goes, so goes the contest).

McCain leads Obama 53 percent to 38 percent, according to results from the poll conducted Monday. That's one percentage point lower for Obama than in the Survey USA poll conducted in the height of the Wright controversy.

Clinton does better than Obama but still below where she was in the Survey USA poll, where she was in a statistical dead heat. Now it's McCain with 50 percent and Clinton with 41 percent.

McCain does well with men against both Democratic candidates but unlike Obama, Clinton has a lead among women against McCain.

But there is some good news for Democrats. Rasmussen also shows Jay Nixon ahead of both leading Republican challengers and says Missouri appears likely to go Democratic in November for governor. For more details on the gubernatorial poll, go here.
