Bull pucky. Liberals are fine with cutting waste and pork, and far more open-minded than conservatives to doing so when it comes to unnecessary military expenditures.
And by the way, have you ever heard of the "Two Santa Clauses" strategy? It was suggested years ago by GOP strategist Jude Wanniski. In essence, it amounts to spend like a drunken sailor when Republicans are in power, then scream bloody murder about deficits when the Democrats are in charge. It certainly looks as if the GOP has been doing exactly that, and the kind of people who depend on the wingnut echo chamber for their worldview just buy into it all uncritically.
