With a commanding performance in the early vote, Mike Siegel, a civil rights attorney running on a Texas progressive populist platform, has moved to a runoff in the state’s 10th congressional district. Siegel won 47 percent of the roughly 40,000 early votes cast, according to a county-by-county assessment, and with nine percent of election day precincts reporting, was pulling in 39 percent. Both totals put him on top of his two rivals, but short of the 50 percent needed to avoid a runoff. In 2018, the 10th Congressional District — which stretches from the Austin suburbs to the Houston suburbs — was written off by the Democratic Congressional Campaign Committee, having gone to incumbent Michael McCaul in 2016 by 19 points. But Siegel, with a focus on organizing a major field operation, closed it to within 5 points. That drew the attention of deep-pocketed donors, who fielded corporate management lawyer Shannon Hutcheson to challenge Siegel for the nomination. Pritesh Gandhi, a doctor who is running to the left of Hutcheson but to the right of Siegel, also jumped into the race, setting up what looked like it could be a rerun of a knockdown, drag-out primary in California that followed a similar trajectory.

In 2016, Doug Applegate ran a lonely progressive campaign against Republican Darrell Issa and lost a surprisingly close race by just 1,600 votes. The blood in the water brought in a school of candidates in 2018; Issa stepped aside, making the seat that much more winnable for Democrats. Applegate ran again, but finished behind the eventual Democratic nominee, Mike Levin, as well as Sara Jacobs, the well-financed granddaughter of Qualcomm billionaire Irwin Jacobs. (Levin won the general election, and Jacobs switched districts, now running for the seat that was vacated by Susan Davis.)
