I'd submit that they're not. For the left, picking on a guy like Santorum is like shooting fish in a barrel. They probably have a template column ripping on social conservatives for things like this . . . all they did was insert Santorum's name into the template and presto.
And puddin hearted “conservatives” like yourself are so terrified of what the democrats might do that your first response is to try and please them.
Moderates are nothing but cowering dogs slinking along behind the democrats begging for crumbs.
