MADISON, WI (WTAQ) - Election officials say they expect a little over one-third of Wisconsin voters to take part in next week’s presidential primary election. That would have about one and a half million people casting ballots and it’s about the same turnout seen in the 2008 primary. The state’s top elections official, Kevin Kennedy, says this year’s contested race between four high-profile Republicans should create that kind of traffic at the polls. Four years ago the Democrat campaign between Barack Obama and Hilary Clinton boosted the number of voters participating.
