AUSTIN, Texas (AP) — Republicans were holding their own Tuesday night in Texas, where Sen. John Cornyn easily won another term and his party grew more confident about keeping control of the state House in America’s biggest red state.

The race between President Donald Trump and Democrat Joe Biden remained too early to call, as were several battleground U.S. House races.

Cornyn’s victory came shortly after polls closed in Texas, where a record turnout of nearly 10 million people in early voting accelerated optimism among Democrats of a breakthrough this year after decades of defeats. But the first wave of results offered no surprises.

Cornyn was headed to a wider margin of victory over Democratic challenger MJ Hegar than the the Texas' high-powered U.S. Senate race in 2018, when U.S. Sen. Ted Cruz squeaked out only a narrow win over former U.S. Rep. Beto O'Rourke.

“I think our friends on the other side had so much money, they had more money than they knew what to do with, so they ended up in a long shot in places like Texas,” said Cornyn, who received a call from Hegar conceding race less than a half hour after polls closed.

Republican Rep. Dan Crenshaw, a rising star in the GOP, won a second term representing his congressional seat near Houston. Ronny Jackson, Trump’s former doctor in the White House, also won a U.S. House race in West Texas

Trump expressed confidence about Texas — which Republicans have carried in every presidential race since 1976 — but polls down the stretch suggested that Joe Biden still had a chance as Democrats saw unusual opportunity up and down the ballot in a state where they’ve been shut out for a generation.

Few problems were reported at polling places as scores of voters continued turning out. In Harris County, a crucial battleground home to more nearly 5 million people, election officials reported that at least another 190,000 more votes had been cast.

James Price, a 55-year-old fork lift driver from the suburb of Tomball, voted for Biden and believed that Democrats were on the brink of making a breakthrough in Texas after years of irrelevance.

“But it don’t matter whether it turns blue or red, green, purple. If these elected officials ... cannot work together, this is not going to work. It don’t matter who flips what,” Price said.

Democrats, shut out of power in the Texas Capitol for a generation, had believed they were within reach of seizing the majority in the state House chamber for the first time in nearly 20 years — an outcome that would mark a new era in what has been America’s foremost factory of conservative legislation.

Although many key House races had still yet to be called, Republican Gov. Greg Abbott tweeted: “Texas DID stay Red.”

Voters in Texas made their pick for president while holding negative views about the country’s direction, according to an expansive AP survey of the American electorate. AP VoteCast found that nearly three-fifths of Texas voters said the U.S. is headed in the wrong direction and about two-fifths said it is on the right track.

In Dallas, retired antiques dealer Cheryl North, 71, said she voted for Trump and every other Republican on the ballot.

“They didn’t have a place on the ballot where you could vote straight Republican but I just went through one at a time,” she said.

She said her biggest motivation to vote was “fear of my country becoming socialist and (I) just didn’t want that to happen.”

Texas has already surpassed the number of ballots cast in the 2016 election. Elections experts predicted the number of votes could surpass 12 million, which would amount to more than 70% turnout — a striking level for a state that was among the worst for turnout in 2016. Turnout among registered voters has not been above 60% in any presidential election sine 1992.

The avalanche of votes reflected high enthusiasm and signs that Texas, where Republicans have coasted in lopsided elections for decades, was rapidly transforming into a battleground.

In Hidalgo County, along the Texas-Mexico border, officials kept voting centers open an extra hour due to “laptop check-in issues” that delayed lines earlier.

The heavily Latino border lagged in early voting turnout behind other parts of Texas, and Texas Democratic Party chairman Gilberto Hinojosa said his party’s decision to not knock on doors for much of the campaign because of COVID-19 worries hurt outreach efforts. Contacting voters by phone, Hinojosa said, is “only so effective.”

Biden was faring far worse along the Texas border than Hillary Clinton did four years ago. For Democrats, the disappointing results along the heavily Latino border came just days after Democratic vice presidential nominee Kamala Harris visited the region in the race's final days.

The road to Election Day in Texas was littered with legal battles over voting access in the middle of a pandemic. Whereas the vast majority of states are allowing widespread mail-in voting because of coronavirus fears, Texas is only one of five that refused, choosing instead to expand early voting by one week.

On Monday, a federal judge rejected a last-ditch effort by GOP activists to toss out nearly 127,000 votes in Houston that were cast at drive-in polling centers. Later Monday night, a federal appeals court panel denied the group’s request to halt drive-thru voting in Harris County on Election Day.

Polls suggested a closer-than-normal race in Texas — which Trump won by 9 points in 2016 — although the president gave little indication of outward concern. He didn’t campaign in Texas down the stretch, focusing instead on tossup battles in Florida, Arizona and Pennsylvania.

Biden did not campaign in Texas either — frustrating Texas Democrats who pleaded with the former vice president to make a bigger push with his chances here looking remarkably viable. He instead ran a relatively small campaign in Texas, and left the heavy lifting to millions of dollars that Democrats poured into down-ballot races to oust vulnerable GOP state lawmakers and members of Congress.
