Polls for Tuesday’s Michigan presidential primary will be open from 7 a.m. to 8 p.m., and registered voters can go to the polls at their usual polling places. If you’re not sure where to vote, go to webapps.sos.state.mi.us/MVIC.

Voters much be pre-registered, but do not have to be a member of a political party to vote in the primary, according to the League of Women Voters. They will have to choose to vote on either the Republican or Democratic ticket, however.
