Texas’ junior senator, Ted Cruz, will headline a key event — the annual Gridiron dinner in Washington, D.C., on March 8.Cruz, who has been mentioned as a potential Republican presidential candidate in 2016, will follow in the footsteps of another Texas Republican, Gov. Rick Perry.Perry was fresh off his failed presidential bid when he spoke at the elite white-tie event for Washington journalists and politicians in 2012. For him, it was a chance to poke fun at himself.Perry noted that his bid to become president failed amid the “weakest Republican field in history and they kicked my butt.”He said his presidential campaign was “the three most exhilarating hours of my life.” As for the GOP presidential nominee, Perry had one thing to say: “I like Mitt Romney as much as one really good-looking man can like another really good-looking man under Texas law.”Last year, Louisiana Gov. Bobby Jindal and Minnesota Sen. Amy Klobuchar were the speakers.Baby timeU.S. Rep. Joaquin Castro, D-San Antonio, and wife Anna recently welcomed their first child, daughter Andrea Elena, on Dec. 15. The latest heir to a political dynasty weighed in at 8.13 pounds and measures 20 inches.“Both mother and daughter are healthy and happy,” Joaquin Castro said in a statement. “We are grateful to the staff at the Methodist Hospital and to all who have kept our family in their prayers.” A senatorial bidA longtime Texas political operative has decided to stay behind the scenes no longer. Ed Gillespie, a former Republican National Committee chairman and a key GOP lobbyist, is gearing up to make his own bid for public office — likely seeking a U.S. Senate seat from Virginia.Word surfaced recently that Gillespie, a former aide to officials including former House Majority Leader Dick Armey and former President George W. Bush, is considering challenging Sen. Mark Warner, a Democrat.His claim to fame also includes serving as an adviser to Mitt Romney during the 2012 presidential campaign and serving as a key writer of the 1994 GOP “Contract with America.”Looking for feedback?The U.S. Postal Service wants to know by Jan. 30 how residents feel about the potential relocation of the historic downtown post office, but they don’t want residents to tell them what they think by email, phone, Facebook, Twitter or on a website.
