There is talk of the Democratic majority in the Senate playing games with the 60 vote minimum to avoid a filibuster.
It is true that each session of Congress can set the rules for the next 2 years.Theoretically they could make such changes.They must be careful, because in 2 years if the Republicans gain control of the Senate, they will not only make new rules but punish the Dems if they restrict the filibuster in this session.
There is an even more relevant reason not to worry.What with such a large majority in the House, it is more likely that the Dems will make more use of the filibuster especially on Obamacare.There will not be a continuous flow of left wing bills from the House as we saw in the last 2 years.
While some are saying that the Rep will not be able to stop Obamacare,the continuous whittling away of funding and mandates will make the law ineffective.
Of course we are waiting for the Fla Federal Court to rule,and then either to the next level or on to the Supreme Court.
