History Made on Capital Hill

No I'm not talking about the House of Representatives. IIRC the senate made history by voting unanimously to extend unemployment benefits and the first house tax credit (98-0) after 3 cloture votes.

Help me out history buffs.

Has there ever been a cloture vote on a bill which went on to pass unanimously ?

How many senators ever voted against cloture then voted for the bill with no new amendments ?

Is the current Republican caucus the most obstructionist minority in Senate history ?

OK that last one it too easy.

This is a new fronteir in obstructionism. The Republicans obstucted a desperately needed bill which they support (they voted yes) in order to generally slow down the Senate. They went all out (3 cloture votes) on this bill exactly because it is urgently needed so Reid wouldn't put it off until after the Senate considers health care reform.

I know the Senate has done terrible things in the past, but somehow this seems to be a new combination of evil, pettiness and hypocrisy.
