Democrat candidate Mary "MJ" Hegar and incumbent U.S. Sen. John Cornyn, R-Texas, were the big winners of the March 3 U.S. Senate primary election. Hegar garnered approximately 82,129 votes, or 20.07%, of all Democrat support across Harris, Montgomery, Fort Bend, Waller, Brazoria and Galveston counties, and Cornyn received 282,137 votes, or 76.92% of all Republican votes throughout the Houston Metro.

Hegar bested the other Democratic candidates statewide, with 22.28% of the nearly 1.85 million Democrat votes cast in Texas, resulting in a May 26 runoff against Texas State Sen. Royce West, D-Dallas, who has 14.52% of votes counted. Third-place candidate Cristina Tzintzun Ramirez received 12.76% of all votes, failing to make the runoff election, which occurs between the top-two candidates if no one receives more than 50% of the vote.

Cornyn received 76.31% of the 1.95 million Republican state primary votes. He will appear as the Republican nominee on the Nov. 3 general election ballot.
