That's exactly what they'll do.
Remember how they raked Bush I over the coals for breaking his "read my lips" promise?
The dems initiated the tax increase in Congress. They forced a gov't shutdown over the issue. And they got Bush to sign a bill, including the tax increase that the RATS voted for.
Then they criticisized him during the campaign for signing THEIR bill.
Actually it was malcontents on the right wing who blamed Bush for breaking his promise and they had Perot to go to even though his wife was on the Board of Directors of planned parenthood.
Anyway CFR is completely different than taxes and if the demos say that he should have vetoed CFR, Bush will laugh right back at their face for doing a 180 on a bill they supported and pushed through Congress.
