Republican gubernatorial candidate Meg Whitman said Wednesday that she probably will vote against a November ballot initiative that would suspend AB32, California's landmark greenhouse gas reduction law.

Whitman, appearing on the conservative John and Ken radio show on KFI in Southern California, said, "In all likelihood I will vote no on Prop. 23," adding that she still backs a one-year moratorium that she would impose if elected. Proposition 23 would suspend AB32 until unemployment drops to 5.5 percent or lower for a year.
