Can the damage be repaired? Of course. It's March. And Michigan voters, being sensible humans, not fools who hold a senseless grudge-- (about a primary that yielded no delegates for them) --forever, will listen to what the Democratic nominee and the Republican nominee say--and vote for the one they think will help their own economic situation.

Regardless of whether a primary "that counts" is ever actually held.

And, as I said, McCain is hemmed in by his own base from offering much in the way of help for Michigan people in economic distress--or people outside Michigan.
