Frankly that doesn't scare me as much as you might believe. Nor does it seem very realistic.
I hope you're right, but there are a lot of things Congress can do against the President's wishes besides overriding a veto (which GW seems wont to do). Remember Slick Willie firing EVERY US Attorney in the US the day he took office? Congress can hold EVERYTHING having to do with funding hostage to get what it wants and the Repubs ALWAYS cave... Mark my words...if they win 2006, they've got 2008, 2012, 2016 and so on.....
