It’s another thing to see how the results of that lopsided election look on a map. Each teal-colored area represents a victory for Medina’s challenger, Monica Ramirez Alcantara:

Bexar County primary for Democratic Party chair

Every registered voter in Texas lives in a voting precinct — a distinct neighborhood or geographic area. Election results for each precinct are available to the public, which means you can plug those numbers into a spreadsheet, add some formulas, and create nifty interactive maps that show which candidate won each precinct.

I made these maps in Google Fusion Tables. Zoom in on your neighborhood, click on your precinct, and see who the voters in your area supported.

After last week’s election, we focused on maps of Medina’s race and a few others. Winners of each election carried the teal-colored precincts:

Bexar County District Attorney Nico LaHood: Lost to Joe Gonzales in the Democratic primary

Texas House District 118: Incumbent Tomas Uresti lost to Leo Pacheco

Bexar County Commissioner Paul Elizondo: Forced into a runoff

Medina told me on Election Day that much of the Democratic turnout was driven by new voters, many of whom were unhappy with the presidency of Donald Trump.

But as my story with political writer Jasper Scherer noted, some of Medina’s critics complained that Medina himself was guilty of sounding like Trump in his own campaign rhetoric. Alcantara said she heard that complaint from Democrats.

“Our constituents wanted change,” she said. “I believe they could see through all of the rhetoric that was going on. I think they used this opportunity to have their voices heard.”

But where are all these newcomers moving to within Bexar County?

Kelly Guckian, database manager for the San Antonio Express-News, pulled together more detailed population figures from the 2010 Census to help show where Bexar County is gaining residents — and where it’s losing them.

Kelly focused on census tracts, which are geographic boundaries set by the Census Bureau that encompass, on average, about 4,000 people. This allowed her to zoom in on population changes at the neighborhood level. She did the tedious work of compiling and mapping the data, and I helped export it into this interactive Google map that shows how the far West and North sides of the county saw explosive gains in the blue areas, while many inner city neighborhoods in the yellow areas lost residents.

Kelly and graphic artist Mark Blackwell also produced maps showing the population trends broken down by race and ethnicity, and MySA’s Mike Howell put it all together in an interesting package online.

The explosive growth on the county’s outskirts occurred during a decade when city officials emphasized the importance of living near downtown and limiting urban sprawl. Our news story about the Census numbers explored why many people either didn’t hear the city’s message — or ignored it.

Somehow my unofficial beat during every election in San Antonio is to roam around and write about the problems and low-voter turnout that afflict our messy Democracy. While on “election snafu” patrol, I was relying on a list of voting sites put out by the Bexar County Elections Department. But the list of locations was in the dreaded pdf form — not a very useful way to see at a glance which sites were in the neighborhoods I was interested in.

It was all relatively painless. I ended up relying on this map quite a bit today as I drove around checking voting sites.

A map like this is useful if you want to see the voting locations in your area. It also helps to show the sheer scale of Bexar County’s network of polling sites.
