It's popular to beat up on Senate Minority leader Mitch McConnell (R-KY) and House Speaker John Boehner (R-OH). Is there another argument to be made? Perhaps so.
John Feehery writing for The Hill makes the argument that these two have done very well indeed. I won't try to summarize all of his points, but certainly letting sequestration take place without caving on more taxes is a big part of it.
