Ken Vogel: “The law couldn’t be more clear: campaigns aren’t supposed to communicate strategy or coordinate spending with their super PAC supporters. And all the candidates claim they’re not doing anything wrong — Santorum insists super PACs don’t come up in his chats with Freiss, and representatives for Gingrich, Romney and Obama all say they’re not breaking the rules either. It looks like they’ll get the last laugh, since there’s no sign of serious legal or technical challenges to the brazen behavior that might force campaigns or super PACs to reverse course before Election Day.”
