Voters in many states will decide on a host of ballot initiatives this Election Day. Here’s a look at some of the most consequential:

Criminal Justice

Almost a dozen states will vote on measures that will change criminal penalties and how they are prosecuted. Floridians could restore voting rights to more than 1.4 million people with felony records, while Louisiana may begin to require juries to reach a unanimous verdict before convicting a defendant of a felony.

A slate of states will vote on a “Marsy’s Law,” which gives criminal victims a larger role in prosecutorial processes. Florida, Georgia, Kentucky, Nevada, North Carolina, and Oklahoma could all enact legislation to give victims more sway.

Voters in Michigan and North Dakota could completely decriminalize marijuana, making it available for legal recreational use. Missouri and Utah could legalize marijuana for medical purposes. The Ohio ballot features an item to reduce drug possession charges to a misdemeanor.

Health Care

Idaho, Nebraska, Montana and Utah each have ballot measures to expand access to Medicaid to low-income adults, in addition to pregnant women, children, seniors and low-income families.

Energy and the Environment

Residents of several states will decide whether to curtail the energy industry in their states. In Colorado, a ballot measure would require oil and gas drilling to take place more than 2,500 feet away from occupied buildings, a major increase from current codes. Florida residents will vote on banning offshore drilling in the state, though that question is also mixed in with a measure to ban vaping indoors. Washington could become the first state in the nation to tax carbon emissions if voters pass a referendum there.

Ballots in California will feature a question about repealing an increase in a tax on gasoline in a bid to help drive Republicans to the polls. Missourians vote on whether to increase their gasoline tax.

Voters in both Arizona and Nevada, two of the sunniest states in the nation, could require the 50% of all electricity to come from renewable sources by 2030.

Voting and Elections

Residents in four states—Colorado, Michigan, Missouri, and Utah—will take on congressional and state legislative redistricting. The ballot measures in each state would create an independent commission or state official to help draw the districts in a move that would mitigate partisan gerrymandering.

Maryland and Michigan are considering initiatives that would allow residents to register to vote on election day. Nevadans will decide whether to make voter registration automatic, requiring people to opt-out of registration rather than opt-in.

Arkansas and North Carolina have ballot measures that would require people to show a photo identification card before voting.
