Don't make him angry. You wouldn't like him when he's angry.

Liberal blogger Matthew Yglesias (though he's hardly alone) took a group of unnamed Bush republicans to task because they admitted partisanship stops them saying publicly when they think President Obama is doing a good job. Quoting the NY Times story:

Some worried they would draw the ire of Cheney’s circle if they did...

And Yglesias' response:

some of them don’t want to say he’s doing the right thing because that might make Dick Cheney mad and they’re timid, gutless careerists?

Now now, Matt. In their defense, he could shoot them in the face.
