THE GREEN LANTERN THEORY OF DOMESTIC POLITICS. To follow up on Ezra's point about Megan McArdle's claim that impeachment proceedings would mean "not having any achievements to show the electorate next year," it's always striking to me the extent to which even many smart, politically aware people don't fully absorb the implications of the Madisonian institutional framework. As Ezra says, as long as the GOP has more than 40 Senators and the White House, major accomplishments are not an issue. This also comes up a lot in debates with my Naderite friends, but while there are any number of valid critiques of Clinton, to attack him for not achieving any major progressive initiatives after 1994 is bizarre; with a Republican Congress this simply wasn't a possibility. The President has a lot of power to affect the implementation of existing policy and can do a lot to obstruct change, but his ability to create major domestic policy shifts without Congress is nil. (And this is applicable to reactionary -- as opposed to merely conservative -- policy shifts as well as progressive ones. As Bush's attempts to privatize Social Security recently and thankfully dramatized, the only thing harder than creating a major new domestic program is rolling one with anything resembling a broad constituency back once it's been implemented.) Another upshot of this is that debates about impeachment are purely about the politics -- obviously there's no chance of 2/3 of the Senate voting to convict anyone. And I also agree with Ezra that here McArdle is considerably more persuasive. It's hard to see how serious impeachment proceedings (as opposed to stepping up use of Congress' oversight powers in general) would strengthen the Democrats' political position. --Scott Lemieux
