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.

  • Data App: Hey, Big Spenders

    By Ross Ramsey and Matt Stiles

    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. Ron Paul, R-Surfside, who contributed at least $240,000 — the highest dollar amount — and Charlie Gonzalez, D-San Antonio, who gave more than 60 contributions — the highest number. Search our database to see who gave what to whom. Full Story
