By engaging in a real on the Senate floor filibuster against a Senate health care bill that includes a strong public health insurance option that's available to everyone.
Not a phantom Republican filibuster, a real one which could be forced by the Democratic Senate leadership.
That would do it.
Bring a final bill with a strong public option out of a House/Senate conference to the Senate floor for an up and down vote.
If a Republican filibusters against the bill, require them to remain on the Senate floor under Senate rule 22.
Keep the legislation alive on the Senate floor until the Republican filibuster ends or until 60 votes are obtained to end debate, whichever happens first.
Now that wasn't so hard, was it?
In current practice, Senate Rule 22 permits filibusters in which actual continuous floor speeches are not required, although the Senate Majority Leader may require an actual traditional filibuster if he or she so chooses.
A filibuster can be defeated by the governing party if they leave the debated issue on the agenda indefinitely, without adding anything else. Indeed, James Strom Thurmond's own attempt to filibuster the Civil Rights Act was defeated when Senate Majority Leader Mike Mansfield refused to refer any further business to the Senate, which required the filibuster to be kept up indefinitely. Instead, the opponents were all given a chance to speak, and the matter eventually was forced to a vote.
