Hopes that a heart transplant would change Dick Cheney have proven unfounded- he's hit the hyperbole a bit heavy in declaring Obama "an unmitigated disaster to the country."
On domestic policy, he comes close to that. On foreign policy, he's actually done an OK job, letting the security forces do their job in getting Osama and keeping Club Gitmo open. With the exception of taking a more pro-Palestinian line on Holy Land policy and being a bit too eager to bug out of Afghanistan, he's been not too far from what a McCain administration would have done.
Of course, Mitt-igation of these errors is coming if the voters so choose. One hopes the changes mitigate things as well.
