In the current Republican race, what’s important is not the winner of the latest primary or caucus, what’s important is who is losing. After all, all of the current candidates have won at least once (except for Ron Paul). As candidates lose momentum and drop out, the winner will not be the person who wins the most often, but the person who doesn’t ever
looselose so badly that they have to drop out, so they keep going long enough to be the last man standing.
So the important news from Tuesday was not that Santorum won. The important news is that Gingrich didn’t even show. Maybe a dead cat is a good analogy for his candidacy (although Derf drew this before Tuesday).
