You must believe then conservative policies will are losing propositions?"
Wow. That's not very good reasoning. I think it's clear in his post that he believes in conservative policies, but doesn't think that Santorum communicates or defends them well.
I happen to agree with him on that point. When Gingrich speaks he makes it sound like you'd be an idiot to disagree with a conservative. Sadly, though he's usually OK, there are times when Santorum speaks that he makes it seem like conservatives are idiots.
In other words he clearly doesn't believe conservative policies are a losing proposition, but rather believes Santorum is a losing proposition.
The false assumption is to actually attribute Newt as being a true conservative. He has been more of an establishment figure than a true Tea Party Patriot in any sense of the word.
Conservative policies will work if they are passed. With a Republican House and Senate, which is likely in 2013, they will pass. That will make a President Santorum very popular.
