SAN ANTONIO (AP) — Texas state Rep. Aaron Pena is personally experiencing the frenetic pace of his state's once-a-decade fight over political boundaries.The former Democrat had bolted for the GOP when his district was redrawn solidly blue, causing him to opt against running for re-election. Then he got new hope from the U.S. Supreme Court that it might go red again.Amid all the confusion, a deadline of Monday looms for some kind of redistricting compromise. The state and a coalition of minority groups must work out temporary maps by then or see the April 3 Texas primaries pushed possibly into May or even later.The redistricting clash in Texas has been driven by new census numbers showing a burgeoning Hispanic population. The stakes are unusually high because it's adding four congressional seats.
