I don't think that's true at all. What power do they have, other than the filibuster (which they could use against any nominee they don't like)? I don't think most Democrats would have considered Alito a good trade for Miers. And the Republicans could have easily put the Democrats on the defensive. Here's a candidate who could not in any way be portrayed as extremist, and who had Harry Reid's seal of approval. If they tried to filibuster her, they would have totally destroyed whatever credibility they might have left with the average voter.
I don't think it's a coincidence that she withdrew from the running right after the unearthing of those speeches of hers from the '90s that put down the pro-life movement.
That was just an example. I didn't think about what the Demons would do for real, but one could never underestimate how low the traitor party would go.
My point is, if at any point at all there is a risk that exec priv might be cvompromised, her nominatinon is DOA.
I read those speeches that are touted as proof of her liberalism, I was less than impressed. But two things for sure, we'll never know how she would have been and Dubya should have thought harder about the nomination. He should realize that the exec priv may be a problem and not nominate her in the first place.
