In the end, Minnesota remained one of the deepest blue states in the nation.
Barack Obama easily defeated John McCain on Tuesday in a state that no GOP nominee has won since 1972, but that seemed until a few weeks ago to be a potential 2008 battleground.
Obama's margin of victory far exceeded the wins in Minnesota recorded by either John Kerry or Al Gore.
An exit poll of voters showed that the coalition he mobilized was both broad and deep, as he held advantages on most issues and among nearly all groups of voters.
"I think two things did it -- first, Barack Obama's message on the economy resonated with Minnesotans," said Jeff Blodgett, who managed Obama's campaign in the state. "Second was the grass-roots campaign we fought here with thousands of volunteers contacting tens of thousands of voters."
The poll, conducted for news organizations in Minnesota and nationwide, showed that female voters left the Republican fold in droves, compared with four years ago.
A similar big shift was seen among the state's youngest voters, its older voters and Protestants. Voters in cities, small towns and rural areas alike peeled away from the GOP nominee, and suburban voters turned away nearly as dramatically.
Obama squarely hit a couple of his campaign's primary targets, running far ahead among first-time voters and those younger than 30, according to the exit poll. But his much-vaunted mobilization of those voting blocs apparently failed to increase their share of the electorate appreciably; the percentage of voters under 30 increased just one point over 2004, while first-time voters were up by two points.
