Timothy P. Carney:

Just as Democrats talk as if any federal budget cuts will result in starving kids and freezing poor people, Republicans invoke hyperbole to defend the Pentagon budget.

Agreed, but Carney is not quite right. It is not just the GOP establishment who have this position, conservatives are big boosters of military spending as well.  Elected Republicans think they have the backing of conservatives on military spending, but Tea Partiers are not necessarily conservatives, ie, they are not one and the same.  And that is where Republicans missed out.  So there is a potential alliance between Tea Partiers and Democrats.
