Arizona, Arkansas, Florida, Georgia, Hawaii, Indiana, Kentucky, Louisiana, Michigan, New Mexico, Ohio, Pennsylvania, Tennessee, Texas and Utah all have deadlines today.
Voters in Mississippi can register by mail through the end of the day. In Nevada, the deadline to register by mail until the end of the day, but can register in person until Oct. 16. Residents in Illinois have an in-person deadline Tuesday but can register online until Oct. 21.
Florida’s Democratic party filed a lawsuit against the state this morning to extend the registration deadline as Hurricane Michael makes its way toward the state. They argued “thousands of ineligible voters will be disenfranchised,” if the registration deadline is not extended.
