More than 8,500 votes were cast in the unscientific poll, with 56 percent voting against bringing the Chicks' music back. So for now, they remain banned from Houston's two leading country stations.

Around the nation, the Chicks are making it back onto country radio. Consultant Rusty Walker estimates that 75 of the 100 country stations he advises have begun playing their music again.

But Houston remains down on the Chicks, because there is a "more traditional country audience" in Houston and strong support for Texas politician Bush, Walker said.
