As the discerning Kate has pointed out in a thread, the classic Cato (or libertarian policy wonk) case for divided government as the best or even only way to slow the growth in federal spending has been revived in many quarters of late. Friends of genuinely limited government, the argument today goes, should welcome and even help in the likely Democratic takeover of Congress as the most effective way to begin to deal with the fiscal damage done by our utterly undisciplined Republicans, both the president and in Congress. Heres the most recent and pretty powerful if not finally persuasive (to me) version of the case for a calculated choice for the Democrats this time. (Actually, I might be persuaded if I thought fiscal policy is the main thing or the most important thing.) Its certainly an argument the Republicans must begin to address to win in November. They have to start talking and acting as if fiscal competence and discpline, not to mention the idea of rigorously limited government, genuinely mattered to them.
