In support of his call to redo the Constitution, Sabato trots out a quote from Thomas Jefferson positing that a constitution is only good for nineteen years. The quote comes from a letter Jefferson sent to James Madison on September 6, 1789. In his response, Madison raised several fundamental flaws to Jefferson’s (and Sabato’s) reasoning. The one most applicable to our times is this one: “Would not such a periodical revision engender pernicious factions that might not otherwise come into existence, and agitate the public mind more frequently and more violently than might be expedient?” Does Sabato really believe that in 50-50 America, we would have any chance at compromising on a new constitution? After all, each side will try to inject its own solution to the “intractable challenges” that Sabato laments.
You think Washington is in a sorry state of affairs now? Just imagine the mess we'd be in if, in addition to fighting Islamofascists, and a Democrat-controlled Congress seemingly intent on legislating defeat in Iraq for their own political gain, we were also in the middle of a very messy, extremely partisan Constitutional Convention? Go read the whole thing.
