The Fox News Decision Desk projected that incumbent Texas Sen. Ted Cruz would defeat his Democrat opponent Rep. Colin Allred Tuesday, winning a third term in the U.S. Senate.

Cruz, 53, fought back, seeking in the final weeks of the campaign to paint Allred as wanting to allow boys to play in girls sports. He also tied Allred, 43, to Vice President Kamala Harris, who was expected to lose the presidential vote in the state, calling the two Democrats “dos liberales,” or, “two liberals” in Spanish-language advertising.

Ted Cruz scratched out a victory over Democratic U.S. Colin Allred on Tuesday night in one of the most watched and most expensive Senate races in the nation, according to NBC News and Fox News.
