This Tuesday night, November 4, political strategists will be closely watching the returns in a variety of elections — from gubernatorial battles in Virginia and New Jersey to New York City's mayoral race to three Pennsylvania State Supreme Court retention races.

Also in Pennsylvania: Philadelphia's district attorney race, with progressive DA Larry Krasner expected to win a third term. Meanwhile, across the United States in California, voters will be deciding the redistricting ballot measure Proposition 50.

All of these races are, to a degree, a referendum on Donald Trump's second presidency.

Although Trump is applauding GOP gerrymandering efforts in Texas and other states, he is angrily denouncing Proposition 50.

In a November 4 post on his Truth Social platform, Trump posted, "The Unconstitutional Redistricting Vote in California is a GIANT SCAM in that the entire process, in particular the Voting itself, is RIGGED. All 'Mail-In' Ballots, where the Republicans in that State are 'Shut Out,' is under very serious legal and criminal review. STAY TUNED!"

Democratic California Gov. Gavin Newsom responded to Trump's post on X, formerly Twitter.

Newsom tweeted, "The ramblings of an old man that knows he's about to LOSE."

Newsom's tweet is generating a lot of responses.

Proposition 50 supporter Pramod Sharma posted, "You're spot on! Trump's claims are baseless rants from a sore loser. Prop 50 protects CA's democracy by countering GOP gerrymandering, ensuring fair representation. Support Newsom's fight for integrity —vote YES on 50!"

Another X user, Peter A. Patriot, wrote, "Every time he starts screaming 'rigged,' you know the polls are bad. The louder the tantrum, the closer the loss. This isn't strategy anymore. It's fear."
