Election 2024 updates: With Arizona, Trump sweeps all 7 swing states

With 538 electoral votes, the Electoral College does contain the possibility of a 269-to-269 tie. Could we run into this situation in the 2024 presidential race? It's possible, though pretty unlikely: According to 538's presidential forecast, there's only about a 1 in 450 chance neither Harris or Trump attain 270 electoral votes. Still, that's greater than zero, so let's look at how this could play out.

If Congress finds the absence of a majority when it gathers on Jan. 6, 2025, to certify the Electoral College results, the Constitution calls for the selection of our national executives via a "contingent election." In that scenario, the 12th Amendment commands the U.S. House of Representatives to "immediately" choose the president from no more than the three candidates who won the most electoral votes — so in a 269-269 tie, that would mean just the two major-party nominees. However, the choice is not based on a simple vote by the House's 435 members as a whole, but instead is decided through a unique system whereby each state casts one vote according to the preferences of each member of that state's House delegation — with states that have tied delegations potentially unable to cast a vote unless a member breaks with their party. To win, a candidate must win a majority of state delegations (26).

Under these rules, Trump would likely hold an edge in a contingent election for president. 538's House forecast shows a tight race for overall control of the House (which, of course, is based on which party controls more individual seats), but Republicans are far more likely than the Democrats to have an edge in the House delegations from at least 26 states in the next Congress. Currently, Republicans hold a majority of the House seats in 26 states compared with the Democrats' 22, while two others (Minnesota and North Carolina) are tied. Yet if we take 538's forecast and rate each state based on the race rating of its most competitive seat that would change party control, the GOP looks favored to control as many as 29 state delegations to Democrats' 20 come January, while Minnesota remains likely to have a tied delegation.

Meanwhile, the Senate would decide who fills the vice presidency if no vice presidential candidate earns a majority in the Electoral College. Unlike the House, a Senate contingent election vote would be based on a vote of the chamber as a whole, in which a candidate needs 51 of 100 votes to win. Additionally, the Senate can only consider the top two recipients of electoral votes, so even if a faithless elector casts a vote for another vice presidential candidate, the Senate would find itself picking between Vance and Walz.

The Senate math favors Republicans to win a contingent election for vice president, too, due to their 9-in-10 chance of capturing control of the upper chamber. Currently, Democrats hold a 51-to-49 majority, including the four independents who caucus with them. But Republicans are essentially guaranteed to pick up a Democratic-held seat in dark red West Virginia to get to 50-50. Next, Democratic Sen. Jon Tester is an underdog to win reelection in Republican-leaning Montana, while Democratic Sen. Sherrod Brown is in a toss-up race to keep hold of his Ohio seat. Democrats are also fighting to defend five seats in key presidential swing states Arizona, Michigan, Nevada, Pennsylvania and Wisconsin, which could also bear some fruit for the GOP. On top of this, Democrats have only a small chance of capturing GOP-held seats in states like Texas and Florida to make up ground elsewhere.

Compared to other issues (like the economy and immigration), education ranks lower as a priority for Americans. According to recent polls from The New York Time/Siena College and Emerson College, less than 2% of likely voters said it was their most important issue. But 92% of adults still said education was an important issue, while just 8% said it wasn't, in an October YouGov/The Economist poll.

Within education, a hot-button topic is school choice, specifically vouchers and educational savings account programs that direct government funding toward alternative and private education. Opponents fear these programs would take funding from public schools; supporters say they critically support parents' right to choose their kids' education.

National polls show that public opinion on the topic is mixed. In an October Noble Predictive Insights/Center Square poll, only 11% of registered voters ranked school choice as the top policy that would improve public education in America, coming in fourth among eight options, after focusing on core subject areas, increasing teacher pay and reducing classroom size.But according to a September Morning Consult/EdChoice poll, over 60% of adults supported school vouchers and ESA programs (although it's worth noting that EdChoice is an advocacy organization that supports voucher programs). A similar poll of only teachers showed a little less than half of them support the same programs.

In November, three states will vote on ballot measures related to school choice. In Nebraska, Referendum 435 will ask voters if they want to uphold or repeal Bill 1402, which sets aside $10 million annually to fully or partially pay for students to attend non-public schools. While an August poll from SurveyUSA/Split Ticket showed respondents to be divided, but largely undecided, on the ballot measure, an Emerson College/Midwest Newsroom poll last month showed almost two-thirds of registered voters are opposed to "using state taxpayer funds to help fund private schools," while only 29% are in favor.

In Colorado, Amendment 80 aims to enshrine a "right to school choice" in the state constitution, including language that opponents believe could lead to a voucher system. And in Kentucky, Amendment 2 asks whether public money should be allowed to go toward private schools. Similar to Colorado, opponents fear Amendment 2 could lay the foundation for a voucher program.

While there are no public polls of the ballot measures in Colorado and Kentucky, OpenSecrets has tracked fundraising by the committees that support and oppose them. In Kentucky, the vast majority of spending has been in support of expanding school choice, whereas in Colorado and Nebraska, those opposing school choice have far exceeded their opponents. Overall, across the three elections, committees against ballot measures to expand school choice have outraised supporters by over $1 million.

Meanwhile, Florida voters will weigh in on another education-related measure: Amendment 1 could make Florida's education system more partisan by requiring candidates for local school board to disclose their political party. Opponents of the amendment say it would bring politics into schools through partisan campaign contributions — although others argue that schools have been a political battleground for many years already. An average of the polls on Amendment 1 show that Floridians are divided on the issue, with 36% in favor of partisan school board elections, 37% in opposition and 27% undecided.

There's a lot more on the ballot today than just the presidential race. A little bit ago, I posted about two governors' races that could flip from red to blue this year. Well, there are also two governors' races that Republicans entered 2024 hopeful that they could flip — but neither has quite gone according to plan.

Initially, North Carolina looked like it was going to be the most competitive gubernatorial race of the cycle. Democratic Gov. Roy Cooper was term-limited, and North Carolina is obviously a major swing state. However, Republicans nominated Lt. Gov. Mark Robinson, who had alienated voters with a litany of sexist, antisemitic and homophobic comments. He was already trailing badly in the polls when news broke in September about racist and salacious messages he allegedly posted on a pornography website's message board. These days, Democratic Attorney General Josh Stein leads Robinson by 10-20 points in most polls.

Finally, in Washington, Republicans have a strong candidate in moderate former Rep. Dave Reichert. However, Democratic Attorney General Bob Ferguson still has the inside track to succeed retiring Democratic Gov. Jay Inslee. In an average of six polls conducted since Oct. 1, Ferguson led Reichert 53% to 39%.

Elon Musk is expected to spend election night with former President Donald Trump at Mar-a-Lago, sources familiar with the matter told ABC News.

As ABC News has previously reported, Trump is hosting multiple dinners at his private club tonight, including one with his close friends and large donors and another with Mar-a-Lago club members, sources have told ABC News.

Musk is expected to participate in at least one of the events taking place at Mar-a-Lago tonight, according to sources.
