The turnout for early voting is breaking records in Travis County and across Texas.
State officials are calling this presidential race "a high-interest election" for voters.
Texas has set a record with registered voters, which accounts for nearly 80 percent of the state's estimated voting population. The state has 15.1 million registered voters for this election, up from 13.6 million in the 2012 election.
The Texas Secretary of State's office said as of Thursday night, early voting numbers have topped four million. The old early voting record was in 2008 when around 3.5 million people cast their ballots. The numbers include the state's 15 largest counties. In this election, it accounts for more than 41 percent of all registered voters in Texas.
