Count me 100% on the side of those who support the concept of Congress attempting to pressure the Fed. Yes, the Fed is supposed to be independent -- but that hardly means that politicians should treat it as The Word From Above. Monetary policy is critically important, and politicians certainly should care about it, and advocate for their preferences. Indeed, I agree with those who say that Barack Obama's failure to do so (albeit by more conventional means, such as jawboning in private and...oh, yeah, actually making appointments to Fed vacancies) has been a huge mistake on his part. If presidents can and should urge the Fed to act, as they have for years, then I see no reason that Members of Congress shouldn't. As Annie Lowery tweeted, the Fed is well-equipped by design to ignore such things.
Granted, on the merits, I agree with David Frum that the GOP position is terrible economics best explained by a preference for recession conditions heading into the 2012 elections (calling it treason, on the other hand, is a bit much, although I suppose fair game after Rick Perry's recent comments). I don't for a minute believe that Republicans would have the same position if they held the White House right now. But that's part of the game; Democrats are welcome to exploit (and produce) headlines such as Stan Collender's "GOP To Fed: Let Economy Fail." Indeed, the GOP position that the Fed's dual mandate (inflation and employment) is a horrible mistake certainly seems to be something that could easily be exploited in 30 second ads.
