Republican incumbent U.S. Sen. Ted Cruz's success was rooted in rural Texas from the Panhandle to the High Plains where he ran up the score.

Ted Cruz has won another term in the US Senate after defeating his Democratic challenger. Cruz defeated Dallas Congressman Colin Allred by 8 percentage points, a much wider margin than during his reelection bid six years ago.

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.
