Figures show that more than 1.7 million Texans in the state's 15 most populous counties voted early in the 2010 midterm elections. That's an increase of about 656,000 votes compared to the 2006 midterms.
The early voting figures released by the Texas Secretary of State's office came on the eve of today's election. Nearly 21 percent of eligible voters cast their ballots early -- compared to about 13 percent in 2006.
The state's 15 largest counties make up nearly two-thirds of the 13.3 million registered voters in Texas. Texas has 254 counties, though many are sparsely populated.
