Romney still a nose ahead in Rasmussen tracking poll; Obama attacks aren't working; Mitt ahead in the Big Four swing states

Today's Rasmussen presidential tracking poll results: Romney 46%, Obama 45%, Someone Else 4%, Undecided 5%.

Another Rasmussen poll confirms something I've perceived: the Obama campaign's attempts to make Romney the issue, much as the 2004 Bush campaign made John Kerry the issue, aren't working.

The Rasmussen analysis of the date is that the fault doesn't lie with the Obama campaign; the problem is that Romney is simply turning out to be a much harder target to hit than the Democrats had expected.

This is big time bad news for the incumbent. With his approval numbers, Mr. Obama cannot afford for this election to be a referendum on his stewardship of the White House.

Meanwhile, Gov. Romney continues to lead among likely voters in all four of the decisive swing states: Florida, North Carolina, Ohio and Virginia.
