There is an old saying: "Democrats fall in love. Republicans fall in line." Romney pretty much has the nomination in hand. As Cheney sees it, it's time for the party faithful to fall in line. I'm not endorsing Romney, just pointing out how the professionals think. Cheney is a concummate professional, and he knows what is expected of him. If he can help the party by campaigning, he will. If he can help the party by sitting on ths sidelines, he will. He's a soldier first.
Anyone who disses Dick Cheney on any level should rot in Hell.
