The Missouri Senate has passed a bill to require local elections authorities to phase out the use of some electronic voting machines.
Under the measure, Missouri voters could only use an electronic ballot machine that produces a paper trail of marked votes.
The legislation allows other types of electronic voting machines currently in use to remain at polling places. But it prohibits local election authorities from replacing those machines because of a malfunction or wear and tear.
The bill, passed with a 22-11 vote on Thursday, also declares the paper ballot as the official ballot of Missouri elections.
