GREEN BAY, WI (WTAQ) - Wisconsinites can start voting on Monday in-person at municipal clerks’ offices.

And both major parties are making a big push to encourage early voting, to try and give their candidates any possible edge in Wisconsin’s presidential and U.S. Senate races – both of which are extremely close.

Tonight, Former President Bill Clinton will encourage early absentee voting when he visits UW-Green Bay. The doors to the rally at the Kress Events Center open at 7 p.m.

First Lady Michelle Obama will do the same when she speaks at rallies in Racine and Wausau today.

Republican National Committee chairman Reince Priebus has been on a bus tour with Senate Republican Ron Johnson and former Congressman Mark Green to promote early voting through the absentee process.

In the 2008 presidential contest, 1 of every 5 ballots were cast before Election Day.

Under the election laws passed in the last session, the in-person early voting period will last for two weeks – and it will end at the close of business on Friday, November second.
