No Republican agreed with Ginsberg...they still voted for her...understanding this was the president's pick, he was elected and it was their duty to vote for her.
politically, we want as many NO votes from the Dems as we can get. we don't want them to be able to say "we voted for Roberts, but this (insert nominee #2) is a out of the mainstream...".
whether Roberts gets 55 votes, or 70 - he still gets in.
