Looks like this discussion is ongoing....
They can argue about ideology all they want but the facts remain that Roberts replaced Rehnquist's position and the Chief Justice slot all in one nomination and Alito has been named to replace O'Connor's slot when and if he is confirmed.
Now who is right or left of whom is another debate. But if the GOP Senators hold together with 51 votes they can seat anyone nominated be it a winger from either side of the ideology spectrum or a moderator. We'll soon see if there are 51 votes.
Take care
Agreed; the facts are as you typed; debating ideology/strategy is another animal altogether.
Let's hope the pubbies grow a spine, support the President, represent the conservatives who elected them, and get Alito through.
