George Will writes in a recent column that the leading anti-Romney candidate, Rick Santorum, is adding some fun to the GOP nomination process. (It’s easy to look “fun” compared to Romney, IMHO.) Will’s closing paragraphs speculate on the politics of Santorum’s candidacy:

Santorum exemplifies a conservative aspiration born about the time he was born in 1958. Frank Meyer, a founding editor of William F. Buckley’s National Review in 1955, postulated the possibility, and necessity, of “fusionism,” a union of social conservatives and those of a more libertarian, free-market bent.

If the Republicans’ binary choice has arrived, and if new technologies of communication and fundraising are repealing some traditional impediments to fluidity in political competition, Santorum can hope to win the nomination. Yes, in 2006, a ghastly year for Republicans (who lost 30 seats and control of the House, and six Senate seats), Santorum lost by 17 points in his bid for a third term. But, then, Richard Nixon was defeated for governor of California six years before being elected president, carrying California.

Even if Santorum is not nominated, he might galvanize a constituency that makes him a vice presidential choice. For Obama, getting to 270 electoral votes without Pennsylvania’s 20 is problematic. But so, just now, are Republican prospects of getting to 270 with their narrowing choice of candidates.
