You may need to re-register to vote. Here's how to do that

Wisconsin made national headlines this week after an Ozaukee County Circuit Court judge ruled that more than 200,000 registered voters will be ineligible to vote unless they re-register. With less than 11 months to go before the 2020 presidential election, the ruling is expected to be appealed and will likely head to the Wisconsin Supreme Court, though given the court's 5-2 conservative majority it seems unlikely to be overturned.

The political consequences of the ruling are potentially enormous. In 2016, Donald Trump won the state by less than 23,000 votes out of more than three million cast. And the ruling hits Milwaukee especially hard. According to a Journal Sentinel analysis, voters in Milwaukee and Madison were disporportationately targeted for removal from the state's voter roll. Voters in those areas account for 14% of the state's registered voters, but received 23% of the 234,000 letters the state Elections Commission sent in October threatening to remove them unless they updated their registrations.

That letter requested voters inform the state if they had moved, or let election officials know if they were still at their same address. Voters who received that letter but did not respond -- and the overwhelming majority did not -- would be ineligible to vote under Friday's ruling even if they did not actually move.

The good news, however, is that registering to vote is relatively easy in Wisconsin. Below you'll find everything you need to know to make sure you're registered when it's time to vote. Because this is a developing story, the safest way to ensure you are eligible to vote is to check your eligibility closer to, but at least 20 days before, election day. You can also register at the poll on election day.

• You haven’t voted in four years or more (and have been taken off the voter registration rolls); or
• You were taken off the voter registration rolls because of being convicted of a felony, and now you’re “off paper” and want to vote again. More info on voting for persons with criminal convictions click here.
