Minnesota is known for a politically active citizenry, with populism being a longstanding force among the state's political parties. Minnesota has consistently high voter turnout; in the 2008 U.S. presidential election, 77.8% of eligible Minnesotans voted – the highest percentage of any U.S. state or territory – versus the national average of 61.7%. This was due in part to its same day voter registration laws; previously unregistered voters can register on election day, at their polls, with evidence of residency.
