As the race to reform Congress began its last campaign day, President Joe Biden and ex-President Donald Trump conducted opposing rallies. Both candidates made last-minute appeals to voters in New York and Florida.

Polls show that they are the favorites to win control of the House of Representatives, but the Senate is a toss-up. Republicans have recently gained momentum in their bid to seize control of both chambers from Democrats. Winning only one chamber would stymie President Biden's legislative agenda.

Even in regions of the country where Democrats often perform strongly, his party is preparing for defeat as the election enters its last day on Monday. He spoke on Sunday at a rally in New York in favor of Governor Kathy Hochul, who is fending off an unexpectedly fierce campaign from Republican contender Lee Zeldin, who is supported by Trump.

Biden referred to the election as "an inflection point" that will shape the next 20 years in his speech. Voters are deciding between two "fundamentally different visions of America" he said in a speech at Sarah Lawrence College.

Trump, who served as his predecessor in the White House, was speaking for over an hour in Miami at the same time. He attacked Democrats for pushing the nation toward "communism."

"Democrats want to turn America into communist Cuba or socialist Venezuela," Trump told the audience members. "To every Hispanic American in Florida and across the land, we welcome you with open open open arms to our [Republican] party," he continued.

Trump also hinted that he would run for president again in 2024, encouraging voters to "stay tuned" for his event in Ohio on Monday.

On Monday, Biden will speak at a rally in Maryland, a historically Democratic bastion. First Lady Jill Biden is traveling to Virginia to help incumbent Congresswoman Jennifer Wexton.

Trump is organizing an evening rally in Ohio for author and longtime Trump critic JD Vance. Republican Governor Ron DeSantis, a potential Trump White House rival in 2024, is in Miami.

According to polls, Democrats' majority in the House of Representatives is set to decline. The outcome of three highly close elections-in Pennsylvania, Georgia, and Nevada-will likely determine which party controls the Senate.

According to experts, more than 40 million ballots have already been cast during the early voting session, surpassing the total number of early votes cast in 2018. There is a good chance that a number of races may be too close to call on Tuesday night because mail-in ballots often take longer to count than votes cast in person.

Election officials are prohibited from starting the count before election day in a number of crucial battleground states, including Wisconsin and Pennsylvania.
