Former California governor and actor Arnold Schwarzenegger waded further into the debate over a proposal to create an independent redistricting in Michigan this week, engaging in a Twitter debate with the Michigan Republican Party over district lines in Los Angeles.

Schwarzenegger, a Republican, recently lent his support to Voters Not Politicians, whose petition to put redistricting in the hands of an independent commission was recently cleared for the 2018 ballot by Michigan's Board of State Canvassers. He is currently fundraising for Voters Not Politicians and three other redistricting efforts in Missouri, Colorado and Utah.

The Michigan Republican Party responded to Schwarzenegger's endorsement on Twitter Monday, posting a picture they said was the district map of Los Angeles. Schwarzenegger responded by saying, "I hope you campaign as well as you Google, because that isn't our map."

Imagine that, a party that wants to keep the status quo of politicians picking their voters. Fair districts work for voters, not parties: CA's leg approval is 44% - up from 14% pre-reform. Oh, and I hope you campaign as well as you Google, because that isn't our map.#justsaying https://t.co/Xs9eD8iwp9 — Arnold (@Schwarzenegger) July 2, 2018

Schwarzenegger recently said he was disappointed the Supreme Court chose not to make any wide-ranging decisions on cases claiming partisan gerrymandering. But he said he was emboldened by successful efforts to implement fairer redistricting practices in California and Ohio, and said he hopes to help other states do the same.

"In California, taking the power of drawing district lines away from the politicians has paid dividends for the people, and I'm so pumped up that Voters Not Politicians is fighting to end the scam of gerrymandering in Michigan," he said in a recent statement.

In a statement issued Monday, Katie Fahey, founder and executive director of Voters Not Politicians, said Schwarzenegger joins volunteers from across the political spectrum in supporting their cause.

"We are proud Gov. Schwarzenegger, one of the Republican Party's major voices on redistricting, has endorsed our ballot proposal and is committed to terminating gerrymandering," Fahey said.

Voters Not Politicians' plan would amend the Michigan Constitution to create an independent redistricting commission. The 13-member commission would consist of five independent members, four self-declared Democrats and four self-declared Republicans.

An opposition group still has an appeal pending before the Michigan Supreme Court to keep the Voters Not Politicians proposal off the ballot, but the high court refused to issue a stay before the Board of State Canvassers meeting.

Attorney General Bill Schuette has also weighed in, filing an amicus brief arguing the independent commission proposed by Voters Not Politicians would create a new entity that "would be free of the usual checks and balances" ordinarily present on government power.

Currently, redistricting is controlled by the Republican-controlled state Legislature. Democrats and other advocates of election reform argue the system as is benefits the party in control and amounts to political gerrymandering.

Voters Not Politicians rallied thousands of volunteers across the state to drum up enough signatures for the proposal, which calls for creating an independent commission in time for the next round of redistricting after the 2020 Census.
