Joan Walsh argues that Cheney is influencing Obama:

It's easy to say this is good news for Democrats. It certainly seems as if Cheney won't be happy until there are two people left in the Republican Party, him and Rush Limbaugh. Gen. Powell? Don't let the door hit you in the ass on the way out. But I also think what Cheney's doing has disturbing political consequences, for the Obama administration and for the country. I'm also starting to worry Obama is internalizing Cheney's values, with a string of bad decisions on torture, culminating in today's move to reverse his prior commitment to transparency and block the release of more torture photos.

I think crediting Obama's decisions on torture and transparency to the ex-VP, inflates Cheney. That said, I think Joan is on to something in noting the corrosive nature of "looking forward," and ignoring people who did not simply torture, but now take to the airways to defend waterboarding.

As for Obama, again, he is who I thought he was. I can't quite get why people feel betrayed, or are even surprised.
