Florida lawmakers are on the verge of enacting a measure that would require election officials to determine early voting sites have a “sufficient” amount of accessible parking, a move civil rights groups say will make it harder to vote early on college campuses.

The provision requires a supervisor of election to ensure any early voting location has “sufficient nonpermitted parking to accommodate the anticipated amount of voters.” The measure passed the Florida legislature last month as part of a bill with a number of election changes. Florida Gov. Ron DeSantis (R) has indicated he will sign it.

As the 2020 election approaches, measures that could affect voter turnout are likely to draw tough scrutiny. Republicans narrowly won statewide races for governor and U.S. Senate last year and Florida is considered a critical swing state in presidential elections.

State Sen. Dennis Baxley (R), who introduced the provision, said he believed the measure was necessary after reading stories of long lines at the polls and people who couldn’t find a place to park. But civil rights groups say the provision is aimed at college campuses, which often require permits to park on campus or have limited space.

“This is not about parking,” said Patricia Brigham, the president of the League of Women Voters of Florida. “Those students with cars, they can hop in their car and go to an early voting site off campus. This about those students living on campus, who don’t have a car and they want to vote early.”

Baxley denied the measure was at all targeted towards college campuses or intended to make it more difficult for anyone to vote.

“I just think it’s reasonable that if you want to have a voting location, you need a certain amount of square footage. You need a certain amount of visibility. You need to have somewhere they can park to get there,” he told HuffPost.

Baxley said the local supervisors of election would have discretion to determine how much parking in a particular area was “sufficient.” He declined to say whether it would be acceptable for election officials to move an early voting location from a central location to a less convenient place to accommodate more parking.

“I really hadn’t thought about the different ways they might approach it,” he said. “Location is one thing that you’re looking at. But the other thing is access. And if there’s no parking, there’s no access for many people.”
