The March primary runoff is set for today, and there are two races in Hidalgo County and two in Starr County on the ballots.

Lita Leo and David Salazar Jr. are vying to become Hidalgo County treasurer, while incumbent Homer Jasso Sr. and Armando M. Guerra are in a contentious race for Justice of the Peace Precinct 4 Place 2.

While the race between Leo and Salazar has been kept under the radar, the battle for JP has raged on.

In many ways, the race between Jasso and Guerra resembles last year’s Edinburg Municipal election. The same players are aligned within the same two factions — one that supports the long-time political establishment and one that supports a new wave of candidates and elected officials intent on forging a new alliance for the city.

Both groups have come under heavy fire, with each airing transgressions publicly on social media, bumping heads both figuratively and literally.

An altercation at the polls last week almost turned physical when the adult children of incumbent Homer Jasso Sr. confronted Miguel Angel “Mike” Garza, one of Armando Guerra’s most ardent and vocal supporters.

The incident highlights a growing tension between the two factions, which are currently warring over alleged voter fraud. Texas Rangers and the Texas Attorney General’s office are investigating the claims.

In Starr County, the incumbents for Justice of the Peace Pct. 1 and 4 will fight to hold on to their positions Tuesday.

Jesse Barrera, currently the JP for Pct. 1, is running against J.M. “Chuy” Alvarez, an attorney.

The incumbent for Pct. 4, Martin Martinez Jr., is being challenged by Roel “Role” Valadez, a local business owner.

Tuesday will once again determine which group gathers strength among voters, who will ultimately decide who will preside over the seat.
