Augusta — A Maine citizens group says it will support a possible referendum challenge to a Republican congressional reapportionment plan if that party pushes its proposal through the Legislature with a simple majority vote.

The Maine People’s Voting Coalition says it will participate in any coalition formed to launch a “people’s veto” effort if majority Republicans opt to pass their redistricting plan with their majority, rather than seeking a two-thirds vote.

Coalition Executive Director Ed Schlick said Sunday that the GOP supported a pending constitutional amendment requiring a two-thirds legislative vote to redistrict the state. He says passing a plan now with only a majority would be hypocritical.

Republicans say they’re prepared to use their majority power to pass a reapportionment plan if a compromise with Democrats isn’t reached for Tuesday’s legislative session.
