Rio Grande Valley voters will have one last chance to cast their ballots in a spate of local races, as well as 10 proposed state constitutional amendments Tuesday.

Edinburg, Weslaco, Alamo, Edcouch and La Joya are all holding municipal elections.

In Edinburg, two seats on the city council are up for grabs, as is the position of municipal judge.

Four people are vying for the Place 3 seat vacated by outgoing Councilman Homer Jasso Jr. — Juan “Johnny” Garcia, Carlos Jasso, Mark Roque and Deanna “Coach” Dominguez. In the event that no one candidate wins more than 50% of the vote, then the two candidates with the highest number of votes will head to a runoff.

At Place 4, incumbent David Torres is being challenged by David White, who recently retired as an Edinburg police officer and once served as the department’s chief.

And for municipal judge, incumbent Toribio “Terry” Palacios is running against Alma Garza.

Meanwhile, in Alamo, voters must decide on three seats on the city commission, as well as mayor.

Diana Martinez is seeking another term as Alamo’s mayor. She is facing Trinidad “Trino” Medina, who vacated his Place 1 seat to run against Martinez.

Running to fill the two years left of Medina’s unexpired Place 1 term are Oscar “Okie” Salinas and Joel Casas.

Places 2 and 4 are also up for a vote in Alamo this November. Place 2 incumbent Pedro “Pete” Morales faces challenger Joseph Sweet, while Place 4 incumbent Maria Del Pilar Garza faces two challengers — Michael P. Benedetti and Lora “LJ” Gioeni.

In Weslaco, Commissioners Letty Lopez and Josh Pedraza, of Districts 5 and 6, respectively, drew no challengers this election season and will each enjoy new three-year terms. However, Mayor David Suarez is being challenged by Alfredo “Duff” Castañeda, a high school psychology and government teacher.

And in Edcouch, after a brief legal battle to cement the city’s disqualification of two candidates, voters will choose their mayor and Place 3 alderman.

Current Edcouch Place 3 Alderman Fred Borrego Jr. has chosen to vie for the seat of mayor and challenges incumbent Virginio “Virgil” Gonzalez Jr. Meanwhile, two men — Carlos Castillo and John Chapa — are running for Alderman Place 3 in Borrego’s stead. At Place 4, Robert Gutierrez is running unopposed.

And finally, La Joya voters must choose their mayor and two commissioners.

Jose Adolfo “Fito” Salinas is seeking re-election as mayor, and is being challenged by Isidro Casanova and Jaime Gaitan.

Three are competing for La Joya Place 2 commissioner — Daniel Flores Jr., Roger Hernandez and Sylvia Cerda Oxford. Another three are vying for Place 4 — Dalia Arriaga, Laura Mendiola Macias and Aurora Ruiz.

Finally, voters will also have a chance to decide on several proposed amendments to the state constitution.

If passed, Proposition 1 would allow an elected municipal judge to hold more than one office at the same time.

Two propositions — Propositions 2 and 8 — deal with water infrastructure. P roposition  2 would allow the Texas Water Development Board to issue up to $200 million in bonds for projects in economically distressed areas, while Prop 8 would allow for the creation of the “flood infrastructure fund” to deal with drainage and flood issues.

Several of the propositions deal with taxation and the disbursement of tax funds. If passed,  Proposition  3 would allow for the temporary exemption of property taxes in areas damaged by a disaster.

Proposition  5’s passage would allow for 100% of revenues from the sporting goods sales tax to go to the Texas Parks and Wildlife Department and the Texas Historical Commission, as originally intended by lawmakers over 20 years ago.

The passage of  Proposition  7 would allow for increased distributions earmarked for education, while Prop 9 would exempt precious metals held in depositories from ad valorem taxation.

And the passage of Proposition  4 would codify into the state constitution the prohibition of a state income tax.

Finally,  Proposition  6 aims to increase the bond amount slated for the Cancer Prevention and Research Institute of Texas to a maximum of $3 billion, while the passage of  Proposition  10 would pave the way for law enforcement animals, such as police dogs, to retire into the care of their handlers or caretakers once their service is complete.

Polls will remain open from 7 a.m. to 7 p.m. Tuesday. Hidalgo County voters may cast their ballot at any available polling place in the county.
