Republicans are a shrinking minority. The voice of the majority cannot be denied for very long.
Democrats controlled the Senate for decades, yet deferred to tradition that allowed Republicans to block much needed legislation. Democrats did not do what Republicans are doing. Republicans, on the other hand, are forcing Democrats to fight at their level. We are the majority. Once Democrats get back into power, given the anti-democratic behavior of the Republican minority while they held power, Democrats might not feel the need to restrain themselves going forward. So, yeah, this is very disturbing if one considers what might happen next.
