Live updates: Multiple key races called for primary election runoffs, AP projects

With 49% of the expected vote in, the Associated Press has projected that Texas Attorney General Ken Paxton will win the Republican nomination for U.S. Senate, defeating four-term incumbent Sen. John Cornyn.

This projected victory comes after Paxton was endorsed by President Donald Trump.

Based on the projection, Paxton will run against state Rep. James Talarico in the November general election.

Harris County Clerk Teneshia Hudspeth has called this primary runoff election day a successful one for the county.

Hudpseth said that all polling locations closed across the county at 7 p.m., but emphasized that everyone who was in line before the polls closed is still eligible to cast their ballots.

According to Hudspeth, over 93,000 Texans voted in person across 160 Election Day voting locations in Harris County, with about 43,000 voting in the Democratic primary runoff and about 50,000 on the Republican side.

Hudspeth said her office received about 430 calls from voters with questions this Election Day, adding that this was a relatively low number compared to other elections.

Hudspeth called this Election Day a success for Harris County, noting that the county is the third largest in the U.S. and the largest in Texas.

With 61% of the expected vote in, the Associated Press projects incumbent Rep. Christian Menefee to win the Texas Congressional District 18 Democratic primary election runoff, defeating longtime Rep. Al Green.

According to unofficial results, the projection is based on early and absentee voting, with no Election Day votes in yet for either Harris County or Fort Bend County.

One key race that a lot of people are watching this evening is for the District 18 Congressional seat.

Longtime Congressman Al Green is going up against former Harris County Attorney Christian Menefee.

Christian Menefee, who has held this seat since February, is going up against Al Green, who has been in Congress since 2005.

This is a district that has seen a lot of changes recently; it was recently redrawn when legislators redistricted the state.

It's important to note that this is a race that shows a bit of a geological divide.

In the March primary, Rep. Menefee won Harris County with 51 percent of the vote.

Rep. Green, though, won Fort Bend County, with 63 percent of the vote.

We've spoken to both Menefee and Green, who both have expressed concern about voting problems in Fort Bend County today. They still urged people to vote if they can, anyway, even if it means filling out a provisional ballot.

ABC13 spoke with voters at Wheeler Avenue, who reiterated the importance of showing up to the polls.

"If you want changes, you have to show up to make them. So, that's why I'm here," voter Latitia Bigham said.
