Mike Siegel and Pritesh Gandhi will compete in the Democratic primary runoff for Texas’ 10th Congressional District on July 14, 2020. The runoff was originally scheduled for May 26, 2020, but Governor Greg Abbott (R) postponed the election due to the coronavirus pandemic. The winner will advance to the general election on November 3. Siegel received 44.0% of the vote to Gandhi’s 33.1% in the March 3 primary election.

Gandhi was endorsed by the Austin American-Statesman editorial board, which said, “District 10 Democrats have a tough choice, but in our view Gandhi has the greatest potential to move the needle in Congress.” The Austin Chronicle and The Houston Chronicle endorsed Siegel. The Houston Chronicle’s editorial board cited Siegel’s 2018 campaign, his environmental platform, and his experience as a teacher and assistant city attorney in Austin as the reasons for their endorsement.

In the 2018 general election, incumbent Michael McCaul (R) defeated Siegel (D) 51% to 47%. In 2016, McCaul defeated Tawana Cadien (D) 57% to 38%. The 2017 Cook Partisan Voter Index for this district was R+9, meaning that in the previous two presidential elections, this district’s results were nine percentage points more Republican than the national average.
