Because this was posted SEVERAL pages ago I thought I would try to finish the point. The Senate in '09 went through various 'phases' of 'filibuster-proof' stages. Note in the table below when the 'Democrat' column has 58 and is added to the '2' in the independent column the result is a 60 vote majority. This constitues the aforementioned 'filibuster-proof' stage. One could argue that the 2 independents are not faithful to the Democrats...but really, do you think that Bernie Sanders or Joe Lieberman would vote with the Republicans?
So, regardless of whether you want to accept it Harry Reid had opportunities to overcome filibusters of cloture. You also seem to think this filibuster activity is specific to Republicans. To be sure they BOTH have done this since the beginning of the US.
