ALTOONA, IOWA – All the Republicans and their proxies are knocking the others – as porkers, individual mandators, illegal immigrant abettors, serial philanderers, and so on. The most interesting line of attack, however, might be Rand Paul’s dig at Rick Santorum as a war-monger.

While this could tap into a serious Republican aversion to our current hyper-interventionism, it also seems that foreign policy is a net loser for Paul. Maybe Santorum is too hawkish for most voters, but Ron Paul’s foreign policy might be too 1792-style for most voters, too.
