Early exit polls from GOP primary in Michigan

From Chris Cillizza at the Post:

McCain, who won the Michigan primary in 2000 during an unsuccessful bid for the White House, hopes to win again in Michigan with strong support from independents and Democrats taking part in the open primary.

However, early exit polling suggests that fewer Democrats and independents were taking part in the Republican primary than did eight years ago, according to ABC News polling director Gary Langer, which would be good news for Romney if that finding holds up. Less than 10 percent of voters in Michigan's GOP race are Democrats while more than two-thirds are self-identifying Republicans, according to ABC News. Among that group, roughly half call themselves conservatives.

The exit polling also found that the economy was the most important issue for Republicans in Michigan, well ahead of the war in Iraq and immigration.
