Polls open across Texas on busy Election Day

CARROLLTON, TEXAS - NOVEMBER 01: Campaign signs are crowded around the Carrollton Public Library where voters can cast their ballots early in this all-important suburb of Dallas November 1, 2018 in Carrollton, Texas

Polls have opened across Texas for Election Day and a strong turnout is anticipated following an early-voting period in which nearly 4.9 million people cast ballots in Texas' 30 largest counties alone.

Some voters stood in long lines at Texas polling places on Tuesday morning after a campaign season that featured the much-watched Senate race between Republican incumbent Ted Cruz and Democratic challenger Beto O'Rourke.

Like other states in what has been a deeply divisive election year, Texas shattered early voting records in big cities for a midterm election.

Fewer than 5 million voters in Texas cast ballots in the 2014 and 2010 midterms, but this cycle could be closer to a high-turnout presidential year.

The Senate race has overshadowed other contests, such as Republican Gov. Greg Abbott's push for a second term against Democrat Lupe Valdez, the former Dallas County sheriff.
