The latest Republican demagoguery...

...is the Balanced Budget Amendment. Ezra Klein has had several good pieces on this topic in the last six months, beginning with the "Worst Idea in Washington" (my emphasis):

It’s so unrealistic that it would’ve ruled all but two of the last 30 years unconstitutional, which means it’s so unrealistic that there has not yet been a Republican president who has proven it can be done. And that doesn’t just suggest it can’t be done: It suggests that when Republicans are actually in power and have control of the budget, they know perfectly well that it shouldn’t be done. They’re just pretending otherwise for the moment.
