Nuclear power is a key issue in Edwards' conservative-leaning Central Texas district, home to Comanche Peak nuclear power plant. The plant is being considered for expansion, and most utilities say loan guarantees are essential for building new plants because of the high costs of financing the projects.
The Flores campaign initially called Edwards' claims dishonest and denied ever speaking against the loan guarantees. But after the Edwards' staff released the audio and specifics of Flores' comments at a Waco tea party event in February, Flores aides said he had changed his mind since then.
Edwards' spokeswoman Megan Jacobs said, "Mr. Flores cannot hide from his real position, no matter how hard he tries."
