Why did Cheney endorse McCain? To hurt him?

Mark Daniels smells a Machiavellian scheme:

The fact is that Dick Cheney loathes John McCain. McCain went after the Bush Administration for what he saw as its incompetent conduct of the war in Iraq. Maybe even more unforgivable from Cheney’s viewpoint was McCain’s criticisms of the Bush Administration’s incarceration and interrogation techniques at Guantanamo.

Obama clearly enjoyed it:



Cheney had to know he would.
