According to this article from The Hill, Democrats are optimistic about their chances in the 2008 Minnesota congressional elections.

"The entry of a trio of top Democratic candidates into races in the state’s three GOP-held House districts in the past 10 days has spurred talk of turning Minnesota into the Massachusetts of the Midwest, electing a congressional delegation that could mirror the all-Democratic slate representing arguably the most liberal state in the Union.

Whether or not the Democrats can achieve such a tall order, the state has quickly turned into a battleground, with as many as half its congressional seats up for grabs in 2008."
