This is the "PreacherGate" thing I've been talking about all day, from the Kansas City Star tonight:

Is Jeremiah Wright affecting Obama's poll numbers?

Sen. Barack Obama hit 50 percent to Hillary Clinton's 44 percent last week in Gallup's daily tracking poll. It was the largest advantage either contestant has had in the race since late February, according to Gallup.

Then Pastor-Gate went viral on Friday. And Obama's numbers have been steadily declining (while his negatives have ticked up). And today Gallup says Clinton is leading 47 percent to Obama's 45 percent. While not statistically significant, Clinton's two percentage point advantage in today's report is a notable shift from last week, the pollster says.

A separate pollster, Rasmussen, also finds the controversy is hurting Obama. And offers a jaw-dropping statistic. Only 8 percent of Americans have a favorable opinion of Obama pastor Jeremiah Wright.

The pollster also found that most voters, 56 percent, said Wright's comments (which included damning America) made them less likely to vote for Obama. The number includes 44 percent of Democrats.

Two-thirds of voters said they had heard about Wright and the controversy. (That prompted Bill O'Reilly to go off on his radio show this afternoon about how could a third of Americans be unaware of this issue. The Obama campaign is probably grateful that it's a third.)

Here's some solace for the Obama campaign and ammunition for the Clinton campaign via a USA Today poll since the survey was done this weekend. Both lead John McCain but Clinton is above 50 percent at 51 percent to McCain's 46 percent. McCain is closer to Obama with Obama at 49 percent and McCain at 47 percent. The two Democrats have overtaken McCain since the last survey in February by USA Today. (Other polls show McCain leading or tied).
