The Political Omnivore blog raises a startling idea:
Could President Obama—by amplifying this fight over healthcare and contraception—help swing more states to Santorum and thus weaken Mitt Romney?
However: one thing is for sure this is Santorum's moment (he just won three states in a surprise upset) and this is Santorum's issue. If there was ever an issue for a hard-right Catholic to get behind? He's the man to do it. Whatever cred he doesn't have on fiscal conservativism (pro-union, pro-welfare, etc.) he's always been dead-center in the social category. ...
If Team Obama is playing this carefully they might be able to both improve Santorum's chances and, if they really do own the mindshare, burn him with it.
