No.
John Samples (writing in the Daily Caller) doesn’t really think so, either. He thinks if Santorum won the nomination and then lost to Pres. Obama, that would be good for libertarians:
….Rick Santorum could be the George McGovern of his party.
Such a disaster might open the door for a different kind of GOP along lines indicated earlier, a party of free markets, moral pluralism, and realism in foreign affairs. Ron Paul has taken some steps this year toward creating such a party. He has attracted votes and inspired activism. His son or another candidate might take up the cause in 2016 and build on Paul’s achievements. Fanciful thinking? Perhaps, but it may take an electoral disaster to free the GOP from the ideas and forces that Rick Santorum represents.
Santorum’s nomination might someday lead to a GOP-libertarian alliance; much more likely, it would just lead to a Democratic victory in November.
