The author’s explanation, while partially true, completely ignores the role of special-interest money in explaining GOP cowardice.  The GOP must cave in order to maintain the flow of K Street money.  If they were to act on principle by seriously reducing government expenditures, K Street cut them off without a cent.  Remember the Artful Dilettante’s First Rule of Politics—Follow the $$$$ !!
