Michigan weighs in:
WASHINGTON (CNN) - Finally, after days of verbal warfare on the trail in Michigan, comes a late appearance by the most-feared campaign force of all: the mighty snowflake.
Michigan is set to receive a few inches of snow today – no blizzard, but perhaps enough to dampen turnout slightly this Election Day.
Who benefits from the wintry gift? Republican Mitt Romney's polling better among those who've sent in absentee ballots than people making last-minute decisions – who tend to be less-motivated to head to the polls. So if anyone in the Republican presidential field gets a slight boost from inclement weather, it could be the former Massachusetts governor. And in a race this tight – most recent polls show Romney and rival John McCain statistically tied – any edge is welcome.
Democrat Hillary Clinton is the only major contender on her party's ballot in Michigan – but that doesn't make the choice any easier for the state's Democrats and Democratic-leaning independents. Do they cast their ballots for Clinton in what is, essentially, a meaningless contest? Do they vote, as some John Edwards and Barack Obama supporters have urged, for the "uncommitted" option on the ballot, potentially forcing a convention compromise (assuming the eventual nominee and national party allows the state's delegation to be seated after all)?
Do they vote in the Republican primary instead of their own – a move that helped lift McCain, who's still their favorite in the GOP field, to a victory back in 2000? Or do they follow the advice of Markos Moulitsas and other activists who've urged them to support Mitt Romney in an attempt to, in his opinion, sabotage his party's general election chances?
Look for the answers to those questions tonight on CNN's Special Election Coverage, and at cnnpolitics.com.
Most of the polls in Michigan close by 8 p.m. ET, though a few western counties will be open until 9 p.m. ET.
