Republicans have shown aggression in the final stages of 2024 compared to past years, but Democrats have risen to the occasion, resulting in both parties seeing eleventh-hour wins and losses across the country.

Republican National Committee Co-Chairwoman Lara Trump said in a statement on Election Day eve that the RNC has enlisted 500 lawyers who are on standby to handle any allegations of voter fraud, which has long been a focus for the GOP.

“Our message is crystal clear: DO NOT CHEAT,” she said.

Meanwhile, Democrats, led in part by prominent left-leaning attorney Marc Elias, have continued to fight in court all year to expand voter access and loosen voting restrictions while arguing that the GOP’s mission causes disenfranchisement. Elias has said he is following about 200 election-related cases that remain pending even as polls open.

Below is a look at the court battles shaping Election Day.

Pennsylvania county makes emergency request to extend voting hours

The RNC joined Cambria County, a red county in central Pennsylvania, to ask a judge to extend polling place hours on Tuesday because of long lines caused by ballot processing hang-ups.

“This morning’s ballot processing issues in Cambria have resulted in delays — this is unacceptable, plain and simple,” RNC Co-Chairman Michael Whatley said in a statement. “Our legal team acted immediately to support extended hours to give voters the opportunity to vote — we need voters to STAY IN LINE!”

Attorneys wrote in a court petition that malfunctions caused “many individuals” to leave polling places without casting ballots.

A judge quickly responded to the petition by extending voting hours from 8:00 p.m. until 10:00 p.m.

Georgia Supreme Court rejects Democrats’ bid to accept late ballots in blue-leaning county

The Georgia Supreme Court ruled in a 5-3 order on Monday that more than 3,000 voters in Cobb County must return their absentee ballots by the time polls close on Election Day.

The decision was a blow to Democrats after the Democratic National Committee, the Southern Poverty Law Center, and the American Civil Liberties Union had sued to allow a portion of voters who received their absentee ballots late to be able to cast their votes after Election Day.

A Cobb County judge granted the request, but Republicans successfully convinced the Supreme Court to reverse the judge’s order temporarily. Any ballots received after Election Day will not be counted as of now but will still be set aside as litigation on the matter continues.

President Joe Biden won Cobb County in 2020 by a comfortable margin, 56% to 42%.

DOJ to observe polling places in Missouri and Texas after batting down legal challenges

The Department of Justice said it is monitoring polling sites across more than two dozen states on Tuesday to check they were following federal election laws, but the announcement received a chilly reception from a few red-leaning states.

Missouri and Texas brought election eve lawsuits against the DOJ over the monitoring.

In Missouri, a judge ruled in favor of the DOJ and said the department could deploy staff to monitor St. Louis polling places. In Texas, the DOJ reached an agreement with the state that involves department staff standing outside, rather than inside, the polling places to conduct monitoring.

Florida’s secretary of state, meanwhile, issued a strongly worded letter criticizing the DOJ for monitoring in his state.

RNC attorneys wrote in a complaint that the Milwaukee Election Commission limited the number of poll watchers permitted in Serb Hall, Good Hope Library, and Capitol Drive Voting Center to two or four per location during early voting.
