This is it. Today is the voters’ day, and America gets some answers.
Will Beto O’Rourke pull off the upset of the year and beat Senator Ted Cruz of Texas in the 2018 midterm elections?
Will Republicans hold onto their majorities in the House and Senate?
Will President Trump’s supporters come out in force at the polls once again? Will a “blue wave” happen?
Will Georgia elect Brian Kemp or Stacey Abrams its next governor — or will the two end up in a runoff, if a libertarian candidate keeps either from breaking 50 percent?
Polls start closing at 6 p.m. Eastern time: here is a full list of closing times.
Here’s what we know:
• In a Texas Senate race that, yes, may come down to turnout, Mr. Cruz’s campaign initially projected that just over six million people would cast ballots. But that was before nearly 4.9 million Texans voted early in the state’s 30 largest counties. Now, Mr. Cruz’s aides believe turnout will be around 7.5 million.
But other Texas political strategists think total turnout may crack eight million — an extraordinary showing in a midterm campaign and one that would indicate Mr. O’Rourke, a Democratic congressman, has found a new reservoir of voters. Keep in mind: Just under nine million Texans voted in the 2016 presidential election.
The energy around Mr. O’Rourke’s candidacy aside, his prospects matter immensely to Democratic senators: If he somehow wins and his party also picks up Senate seats in Nevada and Arizona, they would have an outside chance to claim control of the chamber. To do so, Democrats would be able to lose just one seat — most likely in North Dakota — and would have to hold a handful of states where they have incumbents who appear far more endangered in the polls than Mr. Cruz.
So it’s a stretch. But it’s not impossible, particularly if the Democratic trends that have been on display in the House in the final week also materialize in the Senate.
• Republican Party officials began Election Day guardedly hopeful about keeping control of the Senate — keeping their one-vote majority or going down to a 50-50 split with Vice President Mike Pence able to cast tiebreaking votes.
The Battle for Congress Is Close. Here’s the State of the Race.
The math currently favors the Democrats in the House and the Republicans in the Senate.
They were girding for losses in the House: Strategists in both parties see Democrats on track to win upward of 35 seats. The G.O.P. now holds a 23-seat majority. But neither party was predicting outright victory. As in the Texas Senate race, early voting and likely turnout appear high, which Democrats see in their favor — but the same was true in some states in 2016, and Mr. Trump crushed Hillary Clinton in the Electoral College.
• President Trump wrapped up his three-state campaign swing in Missouri Monday night, joined on stage by the Fox News host Sean Hannity, despite Fox statements that Mr. Hannity would not be a guest. Mr. Hannity gave Mr. Trump a hug and then mocked the journalists in the rally’s media pen as “fake news” — including his own colleagues at Fox.
Mr. Trump focused on Monday on boosting Republican candidates for Senate and governor in the Midwest; his advisers have started preparing him for the possibility of losing the House.
• While strategists and pollsters in both parties agree on a good number of election outcomes at this point, there is one that causes wide divergence: the Georgia governor’s race. Mr. Kemp and Ms. Abrams are fighting down to the wire, and there haven’t been consistent polling results. The governors’ races in Ohio and Wisconsin have also been hard to call.
• In Florida, Mr. Gillum has held a small edge in most polls in the governor’s race, and Democratic officials are cautiously optimistic that he will prevail Tuesday over the Republican, Ron DeSantis. But Republican officials warn never to count out a G.O.P. nominee for governor in the state, which has not elected a Democratic governor since 1994.
And in the Midwest, Michigan Democrats have moved from hopeful to bullish, as the latest internal polling shows Gretchen Whitmer, the Democratic nominee for governor, expanding her lead in the race.
Republicans are holding onto hope from 2016, where Michigan shocked the country by defying polling and backing President Trump. With the Senate race also looking increasingly noncompetitive, the biggest questions about Michigan loom over control of the State Legislature and in three battleground House seats. In hopes of driving turnout and extending her electoral coattails, Ms. Whitmer held a rally Monday with Haley Stevens, the Democrat hoping to flip the state’s 11th Congressional District.
