***Dan Balz asks "What's the Matter With Wisconsin?"

Five days ago the question was, would Barack Obama walk away with Wisconsin? On Saturday it was, why is Hillary Clinton walking away from Wisconsin? By Monday morning, it was, could Clinton win Wisconsin?...

After last week's results, Wisconsin looked like a candidate to extend Obama's winning streak. That is still the way both campaigns see it. But the competition there has intensified in the final hours and seemingly small matters can take on unexpected significance. Which is why the two campaigns spent Monday morning trying to reset the expectations.

One poll shows Obama with a comfortable lead, another shows Hillary ahead. Go figure.

Public Policy Polling found Obama leading Clinton 53 percent-40 percent. McCain led Huckabee 50 percent-39 percent. 

Meanwhile:

The American Research Group Inc. found Hillary leading 49-43.

The same folks have McCain up just 46-42 over Huckabee.

-- A WISC TV poll says  has Obama running better against McCain.

The Madison TV station's poll has Obama with a 49-42 lead. Clinton is up 46-44 on McCain, within the poll's margin of error of plus or minus 4 percentage points. Both Hillary or Obama have big leads on Huckabee.
