Bernstein muses:

"[U]nity" might well be best seen in the abstract not as a potentially good strategy, but as an effect of a party that is shrinking, especially a party that is shrinking because it has become dangerously divorced from normal electoral incentives.  Is that what's actually happening to the Republicans right now?  I don't know!  I do think, however, that it's rapidly becoming probably the biggest current question worth exploring in the empirical or theoretical study of American political parties.
