You're full of crap. She'd have gotten a vote if she wanted it.
You're wrong.
Two "conservative" Senators on the Judiciary Committee TOLD the White House that they would NOT vote Miers out of Committee if Miers' work-related documents were not released to the Senate. These two knew the Constitutional problems with that, and clearly made the play to deny Miers her vote.
Though there are other similar articles, see Krauthammer's article:

By the way, I also believe it is unConstitutional for the Judiciary Committee itself to stop a vote for the nominee by its ability to deny sending the nominee to the Senate.
