Hillary's Move on Mukasey

So now that Barack Obama will vote against Michael Mukasey's nomination for Attorney General--joining his fellow Democratic candidate Chris Dodd, who helped set this chain of events in motion two days ago--here are a couple of things to keep an eye on:

With the Democrats set to debate on national television tonight, does Hillary Clinton run the risk of looking out of place – especially to the party base, which is incensed by Mukasey and which is already bitter with her over her Iran vote a few weeks ago – if she doesn't make a similar move?

And if all of the 2008 Democratic end up opposing Mukasey, will it trickle down to enough senators to place the nomination in real jeopardy?
