By all means, let Tim Tebow's Mom make a commercial. But then you'd better sit respectfully when any other marginal celebrity is spouting off on their own pet political rant.
Tim Tebow gets a say? Then so does Rosie O'Donnell.
Ted Nugent is a deep political thinker? Then so is Avril Lavigne.
Kelsey Grammer and Patricia Heaton are trenchant political commentators? Then take your lumps from Alec Baldwin.
Kirk Cameron and Scott Baio are now your poster boys? Golly, I don't know. Carrot Top and Gallagher? What's their POV? It's hard to riff on Baio and Cameron. They weren't really relevant when they were working steady.
Sauce for the goose is sauce for the gander.
