Here are some interesting firsts in the 2018 midterm elections, so far:

Women candidates:

Most of the early Republican-to-Democratic House flips of the evening were by Democratic women.

• Jennifer Wexton defeated Republican Rep. Barbara Comstock in Virginia's 10th District.
• Donna Shalala won an open seat to replace Republican Rep. Ileana Ross-Lehtinen in Florida's 2th District.
• Mary Gay Scanlon was elected to the House from Pennsylvania, winning in a redrawn 5th District, Chrissy Houlahan won in the state's newly constituted 6th District, Susan Wild won in the new 7th District. They are the first women to be elected from Pennsylvania to the House since 2014.
• Sharice Davids defeated Republican Rep. Kevin Yoder in Kansas' 3rd District.  Davids is Native American, gay and an MMA fighter.
• Mikie Sherrill won in New Jersey's 11th District, picking up the seat held by outgoing Republican Rep. Rodney Frelinghuysen.
• Elaine Luria defeated Republican Rep. Scott Taylor in Virginia's 2nd District. 

They will join women who didn’t flip districts but whose primary wins are sending them to the House:

• Ayanna Pressley in Massachusetts' 7th District became the first black woman elected to the House from the state.
• Alexandria Ocasio-Cortez in New York's 14th District became the youngest woman elected to Congress.
• Veronica Escobar (16th District) and Sylvia Garcia (29th District) became the first Latinas elected to Congress from Texas.

Vice president’s brother: For the first time a vice president’s brother was elected to the House. Mike Pence’s brother, Greg Pence, was elected to Congress in Indiana's 6th District.

First gay man elected governor: Democrat Jared Polis defeated Republican Walker Stapleton to win the Colorado governor’s race and become the first openly gay man to be elected governor.

Voting rights: Florida passed Amendment 4, restoring voting rights to felons. The amendment will restore voting rights to 1.4 million Floridians, the majority black or Latino men. Florida was one of only three states — and by far the biggest — to bar people from voting even after completing their sentences.

NBC News reporter Garrett Haake, reporting from Democratic Rep. Beto O'Rourke's election night party in El Paso, Texas, says the crowd is going nowhere, despite projections that the candidate has lost to incumbent Republican Sen. Ted Cruz. 

The crowd cheered when Jumbotrons announced that Democrats retook control of the House, and chanted "Beto! Beto!" 

Republican Roger Wicker has won re-election to the Senate in Mississippi, NBC News projects.

With 40 percent of the vote in the solidly red state tallied, Wicker had 59 percent and Democrat David Baria had 38.9 percent.

Wicker had been expected to easily win Tuesday night.

Republican Rep. Kevin Cramer has defeated Democratic Sen. Heidi Heitkamp in the North Dakota Senate race, NBC News projects.

With 25 percent of the vote in the state tallied, Cramer, who serves as North Dakota's sole member of Congress, was beating Heitkamp 57.9 percent to 42.1 percent.

Cramer's win — which picks off a seat from the Democrats — boosts the GOP's chance of keeping control of the U.S. Senate.

Earlier this fall, Cramer and Heitkamp had been running a close race, but in recent weeks Cramer opened up a comfortable lead in the polls over his one-term opponent. 

Republicans maintained control of the Senate Tuesday as Sen. Ted Cruz won reelection against Democratic challenger Beto O'Rourke in one of the most closely watched races in the country, NBC News projects.

Cruz held off a strong challenge from O'Rourke, the 45-year-old congressman from El Paso. O'Rourke's unique campaign style and wildly successful fundraising — he raised more than $70 million in his bid for Senate — made the race highly watched, even as the Democrat trailed in the polls.

Democrats have not won a statewide election in Texas since 1994.

With 79 percent of the vote tallied, Cruz was leading O'Rourke 51 percent to 48.4 percent.

NBC News projects that Democrat Sharice Davids will defeat Republican Kevin Yoder in Kansas' 3rd Congressional District, a crucial pickup for House Democrats' plan to regain control.

With her victory, Davids becomes the first openly LGBTQ person elected to Congress in Kansas.

Davids is also one of the first two Native American women elected to Congress — and the pair made history on the same night. Debra Haaland, who NBC News projects is the winner in New Mexico's 1st Congressional District, is also Native American.

Massachusetts voters have elected the first African-American woman to a U.S. House seat.

Ayanna Pressley, who was also the first black woman elected to the Boston City Council, was elected to the 7th Congressional District in Massachusetts.

Pressley did not have Republican challenger. She defeated Democratic Rep. Mike Capuano, a 10-term incumbent, in a high-profile Democratic primary in September.

Earlier Tuesday, Pressley tweeted  her encouragement that people "vote for activist leaders who will work in and with community," adding: "Vote, because this is your democracy & your voice matters."

NBC News projects that Phil Scott, the Republican governor of Vermont, has been elected to a second term. Scott defeated Democrat Christine Hallquist, a former electricity executive.

Hallquist's bid attracted national attention because of her status as the first transgender woman to be nominated for governor by a major party. 

Scott is popular in the Green Mountain State, where voters in this election split their ballots and re-elected independent Sen. Bernie Sanders and Democratic Rep. Peter Welch, according to NBC News projections.
