2024 election updates: Biden angers GOP associating 'garbage' with Trump supporters

According to the California Secretary of State, around 4.2 million mail-in ballots have been accepted by county registrar's offices. In other words, 21% of all of California's 22.8 million registered voters have already cast their ballots.

That percentage varies depending on the county. In Los Angeles County, 13% of registered voters' ballots have been accepted. In Ventura and Orange counties, the number is much higher - almost 22%.

The number of mail-in votes reached record-highs back in the 2020 presidential election, when 86.7% of Californians voted by mail. In total, 80.7% of registered voters cast ballots in the November 2020 contest.

You can't miss their ads on T.V. and radio. Candidates for a handful of congressional seats seem to be dominating the airwaves in recent weeks. Here's a closer look on why so much money is being spent on so few races.

Campaigning in Michigan, Sen. JD Vance was asked if, given Elon Musk's involvement in Trump's campaign, a Trump administration would give preferential treatment to Musk's Tesla over Detroit's Big Three automakers -- General Motors, Ford Motor Company and Stellantis.

Vance said no.

Since 2008, Saginaw County and Michigan have voted for the person who would win the presidential election. Asked by local reporters how important carrying Saginaw County and Michigan is for a path to 270 electoral votes, Vance said it was "extremely important."

"Michigan is one of, if not the very most important battleground state," Vance said.

Michigan is home to thousands of Big Three employees.

A set of state polls by CNN and SSRS released Tuesday found Trump and Harris to be effectively tied among likely voters in Arizona and Nevada.

In the Senate race in Arizona, Democratic Rep. Ruben Gallego faces Republican Kari Lake. Lake is a Trump ally who was one of the most vocal election deniers after the 2020 election, refusing to concede that Trump had lost the presidential election and that she had lost her governor's race.

In Nevada, Democratic incumbent Jacky Rosen races Republican candidate Sam Brown.

They asked that the overseas ballots be segregated to ensure their validity.

Pennsylvania election law only permits ballots to be sent overseas if the applicant is eligible and the office has rarely seen any misuse, representatives from the Pennsylvania Secretary of State argued.

U.S. District Judge Christopher C. Conner sided with the secretary of state's office in his 21-page decision.

"Plaintiffs delayed too long to file their action, they lack standing, they have failed to join indispensable parties, and they have failed to articulate a viable cause of action," he said.

Similar lawsuits filed by the Republican National Committee in Michigan and North Carolina were dismissed by local courts. The plaintiffs have vowed to appeal.
