Midterm elections live updates: Judge orders DOJ to halt threats to election workers

Voters in six states on Nov. 3 will decide whether to approve ballot measures that would amend their state constitutions or state law to make U.S. citizenship a requirement for voting.

The closely watched popular referenda reflect a push by President Donald Trump to crackdown on noncitizen voting based on unsubstantiated claims of widespread voter fraud.

Voting-rights advocates warn they also raise the potential of sidelining millions of eligible American voters.

"Rather than strengthening democracy, [the amendments are] a political maneuver designed to justify future rollbacks of voting rights," said Rashane Hamby with the ACLU of Kansas in testimony last year.

Ranked choice voting (RCV) will be used in the congressional and state races in Maine and Alaska again this year. People in those states will have the opportunity to have their ballot count toward the person with the majority of votes, even if they strongly prefer a third party candidate.

Under RCV rules, voters rank their candidates in order of preference, first, second third, etc. If no candidate gets a majority of No. 1 rankings, votes are transferred from the candidate with the least top rankings to the other candidates based on who was ranked second, third and so on.

Republican Sen. Ted Cruz issued a stark warning for his fellow Republicans during his latest episode of his podcast "Verdict," which dropped Friday.

"We could lose Texas. And by the way, not just the Senate race, we could lose every single statewide race in Texas. That's how close these numbers are," Cruz said.

The senator, who had one of the closest Senate elections in Texas history when he beat Democratic candidate Beto O'Rourke by 2.6% in 2018, said that he has "examined a lot of numbers," when it comes to the latest polling.

"The Democrats are massively out-turning out the Republicans," he said.

Vice President JD Vance will travel to Swanton, Ohio, on Monday for a campaign rally -- one day before Tuesday's high-stakes midterm elections.

Swanton is outside of Toledo, Ohio, and lies within both Lucas County (which leans Democrat) and Fulton County (which leans heavily Republican).

Swanton is part of Ohio's highly competitive 9^th Congressional District, which ABC News ratings shifted from toss-up to leaning Democratic on Friday.

Democratic Rep. Marcy Kaptur, who represents the 9th District, has been a top target of Republicans for several cycles. Her district was redrawn from one Trump won by 7 points in 2024 to one he would have won by 11 points.

Kaptur faces a rematch with Republican state Rep. Derrick Merrin, who she defeated by just 2,382 votes in 2024 on the same ballot as the president.

Monday's will be Vance's third visit to the state since Labor Day weekend and the sixth visit by either President Donald Trump or Vance to the state since Labor Day weekend. The vice president was born and raised in Ohio.
