And you think Miers will sail through with 60 votes ? Why ? Her outstanding qualifications ?
The Democrats could not credibly argue that Roberts did not have the intellectual weight and qualifications for the job. Independent voters respected Roberts and agreed that he was the man for the job. That is why half the Democratic senators ignored the Moveon and ACLU types and voted for him. Nobody outside the Christian Right thinks that Miers has the qualifications for this job.
Because she is acceptable to the Gang of 14.
And they control the show.
As long as they hold, it will only take 51 votes, because they will prevent the Dems from filibustering.
I'd just like to point out that I fit into that "Christian Right" category, and I don't think she's qualified, either.
