DIMINISHING RETURNS. Conservatives have been thumping the low approval ratings of the Democratic Congress as a way of offsetting the lousy standings of the Republican Administration. Now the destroyed CIA torture tapes has been quickly followed by leaks showing that some Congressional Democrats supported waterboarding in 2002. The usual suspects have made much of it:

Lots of people who were talking tough back then subsequently changed their tunes -- out of either a sudden flowering of scruples or an unprincipled desire to go after the Bush Administration with any weapon that came to hand. But, you know, if you're going to say "it was different back then," it really has to be more than just an all-purpose excuse for politicians. It's also a reason not to hang people out to dry for doing what politicians, and the public, wanted back then, when things were so "different." Your call, but Jules Crittenden notes: "Next thing you know, someone’s going to say the Clinton co-presidency thought Saddam had a nuclear program and backed regime change."

For a Party standing squarely against moral equivalence, they expend a lot of energy telling voters that the Democrats did it, too.

I wonder if it will work. We are closer to the 2008 elections than we are to the 2006 elections that put Pelosi and Reid into power. All deserve whipping, but given the choice, whom will the voters seek to punish next year -- the Party of the wheelman, or the Party of Mr. Big?

Some Democrats are forced to say they were wrong to support the Republicans, and some Republicans happily admit that those Democrats were wrong to support them. Sometimes, when you try to reframe the issue, you find that the issue is actually framing you.
