No, it doesn't. A government war on manufacturing explains it. You may not like Santorum trying to pick winners and losers, but someone needs to take a hard look at the government imposed policies that drive manufacturing out and start clearing out the regultory weeds that has made this a hostile place to try and do anything.
Given the choice to build your factory in California, say, a place where they don't want you, and country "x" where they do want you, you can't be blamed for considering the move. Santorum wanted to solve that problem.
And whoever is the next president, we'd better solve it. When you ship your manufacturing abroad, jobs and technological competence goes with it.
The fact that the attacks on Santorum still continue show that he was and is still seen as a threat to the GOPe.
