Social Security reform -- a tactic?

Josh Marshall calls out Jim McCrery for flipflopping on Social Security privatization. I cannot find the post, but a couple of weeks ago the Duke read a warning that Bush' s Social Security push was all a plot to get Democrats to say they were for tax-free savings for everyone, and then eliminate capital gains and dividend taxes. Is anyone else worried that McCrery's tone implies that exact strategy?

To wit (emphasis added):

"I'm convinced the president's approach is worth pursuing in the legislative process."

... and

"I had not thought of the policy rationale they described yesterday."

If he had changed his mind on the President's specific proposal, he would have said his concerns were addressed. Instead, he said exactly what the Duke would have said privately if his objective was to use the President's proposal as a legislative ruse. Folks, Republicans are smart enough strategically to pull something like this. Anyone else pick up any similar clues?
