Bipartisonship?

Politics has been described as the art of compromise - two sides each give a little and get a little, and while the result isn't what either side would like ideally, at least something gets done.  During the Presidential campaign  Obama promised repeatedly that his Democratic administration would focus on bipartisanship.

Well, after two years of Democrats ramming bills through Congress without consulting Republicans, and Republicans saying "No" to anything the Democrats propose (even ideas they themselves had proposed earlier), we now finally have a truly bipartisan bill to extend the Bush era tax cut and unemployment insurance.  And what is happening?  A large number of Democrats, especially in the House, are furious and threatening not to support the bill because it has compromises! The right wing of the Republican party is, of course, famous for demanding ideological "purity", even if it means they lose elections. Apparently Democrats suffer from this same insanity.
