For Cheney to be pushing the envelope on executive power is especially ironic, given the original constitutional status of the vice presidency: That office is a vestigial afterthought tacked on to the Constitution toward the end of the 1787 Constitutional Convention to solve a gaggle of unrelated problems. And it quickly proved more trouble than it was worth.

The vice presidency, in short, was never intended as an independent center of constitutional power--let alone home of a shadow EPA (the rather wonderfully named White House Council on Environmental Quality); the secret architect of national energy policy; and the shameful global detention and torture policies--including the wretched military commission system.

Perhaps we do need to start thinking about why perhaps the most powerful office in the country is not on the top of a ballot, and why its powers are not defined -- or circumscribed -- by any law or constitutional provision.  It's long past time for Congress to take this on. Past legislation has further provided clear channels of responsibility, particularly on military matters. It would be a good debate to have before the 2008 election, when Cheney will start opening the envelopes.
