And they've finally started voting! First up is an amendment sponsored by Sen. Ben Cardin (D-MD) that would decrease the bill's sunset from six years to four. Sixty votes are need for the measure to pass. It's unclear when exactly the other measures, including the Dodd/Feingold anti-retroactive immunity provision, will get votes.

We'll let you know what the results are as things develop.

Update: The amendment fails 49-46.
