Falling on His Sword
This purports to be the inside story of Edwards' departure from the race.
Not Elizabeth's health, fortunately.
The short version: Because of what Florida settled on the Republican side.
Florida made it highly likely McCain will be the Rep nominee. Word is Huckabee will be Veep to keep on board the Christian foot soldiers.
After Super Tuesday, the Republican race will be all settled.
Democrats, who award delegates proportionally (not winner-take-all) won't.
Primary opponent-bloodying could continue for some time, wounding the eventual Dem nominee against a relatively unscathed Republican opponent.
Edwards' staying in the race would prolong that.
So he's dropping out for the good of the party.
