Voting was heavy across the University of Minnesota’s campus-area precincts in Minneapolis today — and so were the arms of young people at almost every corner, waving signs that were mostly of one description: Obama for President. At Marcy Open School in the Marcy-Holmes neighborhood where students mix with plain folks, the line to vote stretched out the door. There and at Coffman Memorial Union on the U of M campus, many university students took advantage of Minnesota’s same-day voting law to cast their first ballots for president. Here’s a 3-minute video after the jump — and don’t take a drink every time you see a sign, or you’re sure to sleep through tonight’s late returns.
