- Joaquin Castro speaks during a recent engagement.
According to media reports, the San Antonio Democrat will run for reelection to the U.S. House in 2020 instead of going head-to-head with Cornyn. Last month, people in Castro's camp suggested he was "all but certain" to take on the Republican senator.
The San Antonio Express-News was first with the story today, which apparently broke out when Castro made an off-the-record comment about the race to one reporter but was overheard by others.
With Castro on the sidelines, that leaves MJ Hegar — who announced her candidacy last week — as likely Democratic frontrunner.
The former Air Force helicopter pilot ran a 2018 campaign against Republican U.S. Rep. John Carter of Round Rock that came came close to flipping the traditionally GOP-held district. Along the way, she built a strong fundraising organization that's still intact.
Democrats have made a priority of gunning for Cornyn, who they see as vulnerable due to the state's changing demographics and the senator's apparent unwillingness to distance himself from President Trump.
But a blue victory won't be easy. Cornyn has already amassed a $5.8 million war chest along with campaign staff and endorsements, Politico points out.
