COLUMBIA, Mo. — Down-ballot initiatives, including three medical marijuana proposals, could help boost voter turnout for Democratic Sen. Claire McCaskill in her fight against Republican challenger Josh Hawley to represent Missouri in the Senate.

McCaskill, a moderate, needs young people and progressive voters next week to drive up her margins of victory in Missouri’s urban centers in case she doesn’t win enough support from rural areas to beat Hawley, the state’s attorney general. Having pot on the ballot may just get her over the line, according to some students in the state.
