Beto O’Rourke

O’Rourke, a three-term Democratic congressman from El Paso, made it a point to campaign in all 254 of the state’s counties. He reached that milestone during an early June rally in Cooke Co. after nearly 15 months of campaigning. In the end, O’Rourke was the most successful Democratic statewide nominee in a generation, but he lost to Cruz, 51%-48%. Cruz received 4.26M votes, and O’Rourke received 4.05M votes.

Six years earlier, Cruz won an open-seat race for a U.S. Senate seat over former state Rep. Paul Sadler (D-Henderson), 56%-41%. Cruz received 4.44M votes to Sadler’s 3.19M, giving Cruz a 58%-42% head-to-head victory.

O’Rourke won 32 counties. Sadler won 25. O’Rourke flipped Brewster, Fort Bend, Harris, Hays, Nueces, Tarrant and Williamson Cos. and otherwise won the same 25 counties as Sadler.

Overall, in the 30 counties with the most registered voters, O’Rourke received 3.58M votes to Cruz’s 2.95M, giving O’Rourke a head-to-head margin of 55%-45%.

In 185 counties, O’Rourke received a lower head-to-head share of the vote than Sadler’s 2012 performance despite campaigning at least once in every county. In 82 counties, O’Rourke ran at least 5 percentage points behind Sadler.

O’Rourke’s worst performances, relative to Sadler, were in Stonewall (-15.9%), Haskell (-15.5%), Morris (-14.6%), Loving (-14.5%) and Newton (-14.5%) Cos. In tiny Loving Co., 15 people voted for Sadler but only six opted for O’Rourke. In Haskell Co., O’Rourke received 302 votes, less than half of the 631 who had voted for Sadler.

O’Rourke did improve upon Hillary Clinton’s 2016 performance in 198 counties. Statewide, O’Rourke finished five percentage points higher than Clinton.

The O’Rourke campaign’s 254-county strategy was not without some successes in rural Texas. King Co. is one of the reddest places in the nation. Donald Trump received 97% of the vote head-to-head against Hillary Clinton there. Six years ago, four King Co. residents voted for Sadler. O’Rourke received six votes, a 50% increase. Whether those two votes were ultimately worth the trip is a question only O’Rourke can answer, but his overall performance in the state’s many smaller counties suggests his campaigning there had little positive impact on the race as a whole.
