In the first 12 days of early voting in Texas, there have been 6,356,493 people voting in person and 837,089 mail-in ballots received. That means 7,193,582 voters have already cast their ballots. And there are 6 more days of early voting.
The 2016 election had the most people voting in the state. In that election, 8,969,226 voted in the presidential election. It looks like voting this year will easily eclipse that.
