Only 53.5% of Hawaii’s total population was registered to vote last year - making Hawaii the lowest state with registered voters, despite having Hawaii born and raised (and now President!) Barack Obama representing the Democratic Party.
The top five states for voter turnout were Minnesota (75%), New Hampshire, Wisconsin and Maine (71.2%), and Louisiana (70.3%). The U.S. Census Bureau report was released on Monday, and concluded that about 131 million people reported voting in the 2008 U.S. presidential election, which was an increase of about 5 million from the 2004 election.
What's interesting to note is that the increase in voters was made up of 2 million more black voters, 2 million more Hispanic voters and about 600,000 more Asian voters, while the number of non-Hispanic white voters remained mostly unchanged.
