More than seven million people have already cast their vote in Texas for the November 3 presidential elections, making experts predict that the state could see historic overall turnout figures of the century, PTI reported.

Since early voting began on October 13, a massive number of people accounting for nearly 43% of the registered citizens in the state, have cast their votes.

A total of 25,658 people voted in person Sunday and 560 mail ballots were returned while 1,090,445 people in Harris County have cast a ballot so far as per Harris County Clerk, the PTI report says.

Although President Donald Trump had won the state back in 2016, like all other Republican nominees have for decades, democratic challenger Joe Biden’s campaign hopes that an early and mail-in voting will turn the state blue for the first time since the late 1970s.

Democratic vice-presidential nominee Kamala Harris will make a trip to Texas on Friday, which is also the last day to cast early ballots in the state.

Joe Biden’s campaign sent an email to Democratic lawmakers Sunday saying the travel plans “will be publicly released momentarily,” PTI reported quoting the Texas Tribune.

It’s not clear yet where in the state Harris, a US senator from California, will campaign.

According to US Rep Lloyd Doggett, D-Austin, the trip comes amid massive voter turnout in Texas.

“As the most recent statewide polls showing Vice President Biden ahead and the historic voter turnout in Central Texas and urban areas across the state indicate, we are changing Texas,” Doggett said in a statement.

“Sen Harris would not be here near election eve were this not a winnable state. And, as Texas changes, we will change our country and our world for the better.” Biden’s wife, Dr Jill Biden, and Harris’ husband, Doug Emhoff, have made campaign stops in Texas in recent weeks. Joe Biden, however, has stuck to more traditional battleground states such as Pennsylvania.

A Dallas Morning News/UT-Tyler poll among likely voters released Sunday shows Biden with a narrow lead over President Donald Trump, 48% to 45%, within the margin of error. The poll was conducted October 13 to 20.

Texas has seen high voter participation during the early voting period, which began October 13. As of Saturday, nearly 7 million Texans had voted, according to the Texas secretary of state’s office, or roughly 40% of all registered voters.
