When the polls opened at 7 a.m. Tuesday, voters were greeted with long lines, the Star Tribune reported.

Traditionally, Minnesota has the highest voter turnout rate for presidential elections in the country, according to CBS Minnesota. In the 2008 election, nearly 78 percent of Minnesotans voted.

Secretary of State Mark Ritchie predicts this election to have a similar turnout, Minnesota Public Radio reported.

But with high such a high turnout, voters should plan for and expect long lines. The best time to vote is in the middle of the day, in between the pre- and post-work rush.

Polls close at 8 p.m.
