A map of Bexar County’s primary election turnout shows where San Antonio residents generally stand on politics: areas outside Loop 410 are home to mostly Republican primary voters while regions inside the loop have a higher concentration of Democrats.

With the exceptions of neighborhoods near Alamo Heights, Terrell Hills, Fort Sam Houston and Lackland Air Force Base, precincts inside Loop 410 had more Democratic than Republican votes during the 2016 primary election, according to data obtained by the Express-News.

Precincts with 25 percent or more turnout in the Democratic primary include neighborhoods in Midtown, Southtown and north of Monticello Park.

On the other hand, affluent communities like Terrell Hills, Olmos Park, Hollywood Park, Hill Country Village, Shavano Park and Fair Oaks Ranch had the greatest amount of Republican voters in Bexar Country.

When the counting ended around 2 a.m. on Super Tuesday, nearly 250,000 ballots were recorded — 131,184 cast Tuesday and 117,459 in the 11-day early voting period — for a 25 percent turnout among Bexar’s 976,842 registered voters.

U.S. Sen. Ted Cruz received 40.8 percent of Bexar County’s Republican votes, while former Secretary of State Hillary Clinton won 66.84 percent of the county’s Democratic votes, according to the election results.

Those results are close to Texas' statewide primary outcome: Cruz won 43.7 percent of the state's Republican votes and Clinton won 65.2 percent of the state's Democratic votes.

Because Texas has an open primary, voters aren't required to register with a party to vote in its primary. Voters are only allowed to vote in one party's primary each election and can change back and forth each cycle, if desired.
