Their votes were cast on May 26, 2001. Bush signed the tax cuts into law on June 7, 2001. Here we are in mid-July, eight years later, struggling to get health care reform passed by the end of the year.
So whatever these four foot-draggers are saying about why they want health care reform slowed down (and Nelson, for one, was all over the place yesterday warning against "rushing into this"), it's not really about wanting to be more deliberative or avoid ballooning the deficit. All you have to do is look back to 2001. Their records speak for themselves.
