Campbell says what is more important than a pledge is Bush’s record on taxes.

“He didn’t raise taxes,” Campbell said. “He cut them every year as governor for a total of more than $19 billion in tax relief. He does not support raising taxes and believes cutting taxes and reforming the tax code will lead to greater economic growth and more prosperity for Americans.”

Norquist isn’t buying it.

“Most pledge takers keep the pledge,” Norquist said via Twitter. “Those who refuse to sign all raise taxes when pushed hard enough by spenders.”
