We all know George W. Bush doesn’t like to admit mistakes, preferring to flip-flop without acknowledging it when mistakes become unsustainable. And we also know that he has gone longer without vetoing a congressional bill than any president in living memory–rarely even rattling a veto pen as a threat.So what to make of his sudden announcement late last week that he would veto any effort to change the 2003 Medicare Rx drug bill that’s become an ongoing source of embarassment to the administration, and a potential multi-facted disaster in the future?It’s hard to find a recent domestic policy initiative that was born in such a series of Keystone Kops capers. The administration’s claims that the benefit would cost a mere $400 billion over five years–a number that only passed the laugh test because the benefit’s implementation was deliberately delayed until 2006–was widely disputed at the time. The House, famously, had to keep the roll call open for, oh, about fifteen times the normal period in order to get the votes to pass it, and succeeded, famously, only after a series of thuggish threats and blanishments, one of which earned Tom DeLay one of his three reprimands from the Ethics Committee last year.Meanwhile, as GOPers high-fived themselves for coming up with an approach to a hot-button issue that would stoke up health care industry donations while making seniors feel all warm and cuddly inside, the ink was barely dry before it became apparent old folks didn’t much like it. Even the easy part–accepting a drug discount card–wasn’t popular, even though millions of Medicare beneficiaries were signed up automatically. And as we get closer to the implementation of the full Rx drug program, with its steep premiums, skimpy coverage, and wildly complicated structure, it isn’t likely to become the biggest senior sensation since Viagra (even if Viagra is, as reported, covered by the benefit).I mention all this to provide the proper perspective for Bush’s banty rooster crowing about his brave stance in defense of his Medi-Mess.”I signed Medicare reform proudly and any attempt to limit the choices of our seniors and to take away their prescription drug coverage under Medicare will meet my veto,” quoth he, calling the Rx drug benefit “a landmark achievement in American health care.”It was a landmark, all right, but not one of achievement, but of obfuscation and deliberate efforts to mislead the country in the dogged pursuit of power.
