These early polls must be viewed as snapshots during a long and tedious roller-coaster campaign. The latest economic hiccups fueled by Euro worries aren’t helping the president, who has also chosen the early goings to announce his positions on same-sex marriage and immigration. In the meantime, Gov. Romney–unfettered from fellow GOP challengers nipping at his ankles–has changed whisper campaigns from “Obama could lose” to “Romney could win.”

The Michigan results are particularly intriguing. While Romney can lay claim to Michigan roots, it didn’t seem to help him greatly in the Primary, and President Obama’s economic recovery program that bailed out the auto industry should arguably give him a leg up here. The fact this this and other polls have the race so close at this point doesn’t bode well for conventional wisdom in the Wolverine State.
