Lieberman may have deep concerns that a Democratic House would succumb to the folly of seeking to impeach Bush and, thus, risk being thrown back into a minority come 2008
Personally, I don't think they'll have the numbers to impeach Bush. Lets face it if the Democrats do gain control of the House it will be in no small part to the success of moderate candidates in "red" (for want of a better word) states
Nevertheless, the House will rightly scrutinise the executive and its decisions

Either Lieberman is a Republican or he's a concern troll that might as well be a Republican.
