Missouri has open primaries — Missourians can vote for Bernie Sanders regardless of their registered party.
You must have been registered to vote by Wednesday, February 17th in Missouri.
Missouri requires you to present identification in order to vote in person. Acceptable forms of identification include any ID issued by a federal, state of Missouri, or local agency; any ID issued by an institution of higher education; a copy of a current utility bill, bank statement, paycheck, government check, any other government document that contains your name and address; or a driver's license or state ID card from another state.
If you are a college student not living in your home state, you can vote for Bernie in either your home state or in the state in which you are attending school!
If you are a military voter or a United States citizen living abroad, you are able to request a ballot here.
