Russ Feingold, a three-term Senator from Wisconsin and a key ally of President Obama, is in danger of losing his seat to Republican and Tea Party-backed candidate Ron Johnson. Wisconsin election officials are predicting a near record voter turnout today of 50 percent, based on requests for absentee ballots.

The weather is expected to cooperate and not be a hindrance to voters trying to reach the polls.

However, there have been reports out of Verona, Wis. of unreadable ballots. As a result, all of the town’s ballots will be counted by hand. And in Brookfield, voters were given ballots for the wrong district, something that may impact local races but should have no effect on the Senate race.

More reports of ballot problems were brought up in Brookfield, Wisconsin earlier today, where ballots in Wards 15 and 16 had been mixed up, affecting 40 votes and 20 ballots. There were also reports of misprinted ballots in Racine, which has since then been rectified. In Thiensville, officials have requested for 300 more ballots to be printed each for Wards 1, 2, 3 and 4. 

One man was reportedly arrested for voter fraud. The 74 year-old man is accused of voting twice by absentee ballot.
