AUGUSTA, Maine (AP) Maine Republicans are nearing the end of a new push to try to block a ranked style of voting from the state’s presidential ballot.

Voters in the state approved of ranked choice voting in 2016, and it has since been applied to several races in the state, including congressional races.

The voting style allows residents to rank candidates, and subsequent tabulations redistribute their votes. The Maine GOP has organized a petition drive to try to overturn the use of ranked voting for president.

The Republicans have until June 15 to collect the requisite signatures.
