Bexar County District Attorney:

The Democratic primary for Bexar County District Attorney has turned into the most contentious race on the March ballot.

Nico LaHood, the incumbent, is trying to fight off longtime defense attorney and former prosecutor Joe Gonzales, with whom he used to share a building.

Gonzales, a relative political unknown as recently as a few months ago, has been jettisoned by an influx of donations from a George Soros backed political action committee. LaHood as recently as Monday said the contributions had topped $1 million.
