In the above nowhere did I say the left was involved with sinking Miers. I said the "right was eating its own over Miers". I would of thought that was pretty clear.
By "opportunity" I was saying the left saw Bush in a weakened state.
And so the left stepped up to the plate and started swinging.
That "started swinging" was referring to attacking Bush over the war, not Miers. With the Libby indictement they had multiple fronts to attack from. They had something to stick the dishonest tag too now besides just the WMD.
There were numerous Editorials from the right saying Bush's presidency was basically over because of Miers. The left was listening.
You add it all up and here we are.
