Will Hurd (R), a former CIA officer, is initiating a 2010 campaign against Rep. Ciro Rodriguez (D).

Hurd this week filed papers with the Federal Election Commission to run in the 23rd, a Hispanic-majority area that takes in the south side of San Antonio and most of Texas’ border with Mexico.

Hurd, who served primarily in southeast Asia, is the second Republican to organize a challenge against Rodriguez. Also running in the March 2 primary is Francisco Canseco, a wealthy lawyer who lost a primary election for the seat in 2008.

Rodriguez represented Texas’ 28th district from 1997 through 2004, when he was defeated in the primary by now-Rep. Henry Cuellar (D). After losing a rematch to Cuellar in 2006, Rodriguez was elected in the 23rd district that December, aided by a court-ordered partial redrawing of Congressional districts that enabled him to defeat Rep. Henry Bonilla (R). In the 2008 election, Rodriguez defeated Lyle Larson (R) with 56 percent of the vote.
