The poll was conducted just as Romney's 47 percent comments made national headlines. Yes, the comments had an impact on the poll results. However, there is more to it, according to political pollster Richard Czuba.

"Clearly we are seeing a very successful Democratic National Convention for the state of Michigan. Is this just a bounce?" Czuba said.

Are the presidential numbers just an aberration? Judging by the numbers for U.S. Senate, the answer is no.

Democrat Debbie Stabenow is charging ahead of Republican Pete Hoekstra. Her double-digit lead is even higher than Obama's. She is up 16 points -- 49.7 percent to Hoekstra's 33.8 percent.

Czuba has a word of caution about how things can drastically change.

"Let me say this: Our poll has (Romney) losing right now by double digits. At this time in 1990, John Engler was losing by 26 points and he won on election day. Comebacks are possible," the pollster said.
