Texas Candidates Rush to Raise Money by July Deadline

Tonight is the legally imposed reporting deadline for the next round of campaign finance reports, which is big deal for two reasons: Candidates want to show momentum and credibility at mid-year, and they love having an excuse to ask supporters to pony up before the clock strikes midnight.

Cities Collect $100 Million From Red-Light Cameras

Revenue from Texas red-light cameras soared in 2009, with cities collecting more than $62 million from motorists, newly released state records show. We've taken that revenue data to create an interactive visualization that shows how the traffic camera revenue, expenses and profits vary from city to city, along with the proportion of the money that goes to the state.

U.S. Census Bureau Releases TX Population Estimates

Texas now has about 24.8 million residents, an increase of 3.9 million, or almost 20 percent, since 2000, and trails only California in the proportion of its residents who identify themselves as Hispanic. We're also the third-youngest state, with a median age of 33; only Utah and Alabama have younger populations. These and other fun facts can be discovered in a new database application that helps explain and visualize how the makeup of Texas counties has changed since the last U.S. Census.

Census Releases Texas Population Estimates By County

The U.S. Census Bureau's latest county population estimates show that Texas is getting more racially and ethnically diverse. Texas minority population now exceeds 50 percent, as it does Hawaii, New Mexico, California and the District of Columbia. These are the last county estimates to use 2000 Census results as a base. The 2011 population estimates will be the first in the estimates series to be based on the 2010 Census population counts.

Texas Congressmen Give to Each Other

It's not only rich people and lobbyists and interest group activists who make political contributions. Texas congressional candidates gave at least $1.3 million to other campaigns and causes over the last 15 months, according to itemized records of campaign expenditures released for the first time by the Federal Election Commission. Topping the list of big spenders in the Texas delegation were U.S. Rep.

Internationally Trained Doctors Work in Texas

That’s right — they’re not from Texas. Newly licensed physicians enlisting to treat the state’s Medicaid and Medicare patients are more likely to have been trained at international medical schools, according to a review of state medical licensing data.

Map: Internationally Trained Doctors

Of the roughly 1,500 doctors who have received fast-tracked licenses in the last three years for agreeing to treat Medicaid and Medicare patients, about 40 percent were trained at international medical schools, while just a quarter were trained at Texas medical schools. The Texas Medical Board fast-tracked more licenses for doctors trained in Pakistan — halfway around the globe — than it did for doctors educated in neighboring Louisiana or Oklahoma. Scroll over our interactive world map to see where these internationally-trained doctors got their medical education.

But Houston's policy is remarkably similar to that of Texas DPS under Perry. If Houston is a sanctuary city, why isn't Texas a sanctuary state?
