Krugman spells out the consequences should the Republican take the House:
We already know part of the answer: Politico reports that they’re gearing up for a repeat performance of the 1990s, with a “wave of committee investigations” — several of them over supposed scandals that we already know are completely phony. We can expect the G.O.P. to play chicken over the federal budget, too; I’d put even odds on a 1995-type government shutdown sometime over the next couple of years.
It will be an ugly scene, and it will be dangerous, too. The 1990s were a time of peace and prosperity; this is a time of neither. In particular, we’re still suffering the after-effects of the worst economic crisis since the 1930s, and we can’t afford to have a federal government paralyzed by an opposition with no interest in helping the president govern. But that’s what we’re likely to get.
Imagine all of that crap from the 1990s -- the nonsensical investigations, the impeachment, the ridiculous debates about school uniforms and midnight basketball, the government shutdown -- all piled on top of economically perilous circumstances. That's a Republican House majority.
If you're into endorsing an extended round of unserious GOP grabass, by all means, go into the voting booth growling and raging about communism and deficits and lean on the button for Republicans. If not, tell anyone who will listen to wise the hell up and do the smart thing.
