The problem for these pundits is not that Gingrich is Maximus, manipulating the mob to get ahead. Their problem is that Romney is Commodus, the political heir of dubious legitimacy who tries but fails to co-opt the mob. Ironically, their Circus Maximus of criticism is being staged at the very moment when Gingrich looks to be losing momentum. It would be even more ironic if Gingrich could again turn the criticism of his supporters to his advantage.
