Looking past Tuesday's contests

Bob Herbert has a good column on the subject today, as well as a great line about the potential fallout:

When does a dandy fight become an ugly brawl?

For the Democrats, perhaps on Tuesday.

If Barack Obama wins in either Texas or Ohio, the race for the nomination will effectively be over. At that point the Clintons, if they have any regard for the fortunes of the party, will be duty-bound to graciously fold their tents and try to rally their supporters behind a candidate who will be stepping into a firestorm of hostility from the other side.

If Hillary Clinton wins both Texas and Ohio, the Democrats will need a trainload of aspirin and a shrink.
