Midterm election results updates: Dems keep control of Senate with Nevada win

Political heavyweights are hitting the trail for one final day of campaigning before voters head to the polls Tuesday.

President Joe Biden will join a virtual reception Monday afternoon for the Democratic National Committee before heading to Maryland with first lady Jill Biden to stump for gubernatorial candidate Wes Moore and the Democratic Party. The rally at Bowie State University will kick off at 7 p.m. ET.

Jill Biden’s also headlining a rally for Democratic Rep. Jennifer Wexton in Virginia at 11:45 a.m. ET.

Vice President Kamala Harris will spend the day in her home state of California. She and second gentleman Doug Emhoff are delivering remarks at a political event at the University of California, Los Angeles.

Former President Donald Trump is going to Dayton, Ohio, to rally GOP voters. Senate candidate J.D. Vance, who faces Democratic Rep. Tim Ryan in tomorrow’s race, will speak ahead of Trump. Trump will take the stage at 8 p.m. ET.

The National Association of State Election Directors is urging patience ahead of the midterms, saying officials have been working nonstop to ensure the election is secure.

"State and local election officials have contingency plans in place so voters can have confidence in our elections and that the results will be tabulated accurately," the National Association of State Election Directors said in a statement Monday. "As with any election, it is important to note that operational challenges may arise."

The group says it’s normal for ballots to be counted in the days following the election.

"While the focus on election night is on who won and who lost, election night results are always unofficial. In the days and weeks to come, election officials will count every eligible ballot within the bounds of state laws, including provisional ballots, mail ballots, and ballots cast by military and overseas voters,” the statement said. “This critical process is normal, as it takes time to accurately tabulate millions of ballots. Some races will be close and may require a recount or a recanvass, depending on the state, but every eligible ballot will be counted as cast.”

Americans may not know the results of each race on Election Day, or even the following day.

"It takes time to count all legitimate ballots in a legal and orderly manner," President Joe Biden advised last week.

Elections in the U.S. are decentralized, and each state has different systems for regulating races. Some, such as Arizona and Colorado, allow officials to start processing mail-in ballots before Election Day. Others, like Pennsylvania and Wisconsin, can’t begin counting these ballots until Election Day.

FiveThirtyEight has created a sliding scale estimating how long it may take each state to count ballots based on when each state reported results in its primary elections earlier this year.

Nearly 200 candidates running on Tuesday have rejected President Joe Biden as the legitimate winner of the 2020 election. These candidates have either stated the election was stolen or took action themselves to try to usurp the results.

According to FiveThirtyEight, 60% of Americans will have an election denier on their ballot.

Not all Republicans on the ballot, however, are embracing former President Donald Trump’s lies about the race. A total of 77 have fully accepted the results while another 93 have accepted the outcome, with some reservations.
