Santorum's very good night

I concur with Kevin Drum:

So Rick Santorum won three states last night. Does this mean we all have to pretend to take him seriously for the next three weeks? I'm feeling a little queasy over the possibility already. At the same time, I'm getting ready to concede that my valiant efforts to show that Mitt Romney isn't really all that strongly disliked were misguided. Republican voters just don't like the guy, do they?

No, they simply don't.
