Richard Viguerie has an interesting observation regarding the methodology of Ron Paul’s campaign intended to leave Paul as the last not-Romney standing, Ron Paul Goes Bird Hunting:

Experienced bird hunters and fighter pilots know you don’t aim for the leader of a flight — you start at the back of the flight and work your way forward.  This is apparently what Congressman Ron Paul is doing to his opponents in the race for the Republican presidential nomination.

Rather than aim at purported frontrunner Mitt Romney (who should be the number one target of his libertarian supporters), Ron Paul has been working his way through the flock of less well-funded and less well-defined opponents, thinning the field as he goes.

After raking former Speaker Newt Gingrich with fire in Iowa, the libertarian-oriented congressman from Texas has been zeroing-in on former Pennsylvania Senator Rick Santorum in South Carolina.

And zeroing in on Santorum he is, In South Carolina, Paul Renews Santorum Attack:

Santorum’s response? Repeat Newt’s mistake in Iowa of not counter-attacking on television.  Santorum may not have the money or may be conserving money for a longer fight, but getting dragged down by Paul in South Carolina (which appears to be working) may damage Santorum even worse than Iowa damaged Newt.
