Question about polling data

[thereisnospoon]

If Obama is doing such a great job, as the incumbent, why does he not have a 20% lead or more in the polls.
According to the Main Stream Media, and the libs on this board, Obama is a wonderful president, wildly popular. His policies are working so well. Amzingly popular economic and foreign policy. Saved GM, killed bin Laden, created over 4 million jobs...
So why is Obama struggling to hold even the smallest advantage over the challenger?
Even with polling data that is skewed to democrat voters?

The real question is with the economy still in very bad shape, why is Romney not up by 20 points? The incumbent always takes the blame if things are going just hunky dory. So why is Romney only even with Obama? This should be a cakewalk for Republicans, but it is turning into a potentially devastating loss.
