LOS ANGELES — Former Gov. Arnold Schwarzenegger, who championed the creation of an independent commission to draw California's congressional districts, returns to state voters' TV sets on Tuesday in a new ad opposing a November ballot measure by state Democrats to boost their party's ranks in Congress.

A committee opposing Proposition 50, which would replace districts drawn by an independent commission with ones crafted by partisans, plans to spend $1 million per day airing the ad statewide. Schwarzenegger describes the ballot measure as one that does not favor voters but is in the interest of entrenched politicians.

"That's what they want to do is take us backwards. This is why it is important for you to vote no on Proposition 50," the Hollywood celebrity and former governor says in the ad, which was filmed last week when he spoke to USC students. "The Constitution does not start with 'We, the politicians.' It starts with 'We, the people.' ... Democracy — we've got to protect it, and we've got to go and fight for it."

Redistricting is the redrawing of congressional boundaries that typically occurs once a decade following the U.S. census to account for population shifts. The process rarely attracts the attention it has this year because of a heated battle to determine control of a closely divided Congress in the final two years of President Donald Trump's tenure.

After Trump urged Texas and other GOP-led states to redraw their congressional districts earlier this year to boost the number of Republicans in the House, California Democrats, led by Gov. Gavin Newsom, countered by putting a rare mid-decade redistricting on a special-election November ballot that would likely boost the number of Democrats in the body.

Schwarzenegger, long a champion of political reform, is not part of any official Proposition 50 campaign. Since leaving office, he has prioritized good governance at his institute at USC and campaigned for independent redistricting across the nation.

His remarks were filmed, and the ad is being aired by the most well-funded effort opposing Proposition 50, which is bankrolled by Charles Munger Jr., a major GOP donor who underwrote the ballot measures that created California's independent commission.

Munger has already donated $30 million to a campaign opposing the November ballot measure, according to fundraising disclosures filed with the secretary of state's office. The other large opposition effort has raised more than $5 million. The main group supporting Proposition 50, led by Newsom, has raised more than $54 million.

These fundraising figures are based on required disclosures of large contributions. More complete fundraising numbers must be filed with the state on Thursday.
