A Michigan state poll is out:
"Presidential candidates Barack Obama and John McCain are locked in a tight race to win Michigan, according to a Detroit News-WXYZ Action News poll. The results emphasize why both camps consider this one of the battleground states that could determine who's victorious in November. Obama has the support of 43 percent of likely Michigan voters, to 41 percent for McCain, according to the survey conducted for The News and WXYZ by Lansing's EPIC-MRA. That's well within the survey's 4 percentage point error margin."
12 percent remain undecided.
Remember that, if I recall correctly, no Republican presidential candidate has carried Michigan since the 1980s.
