John Boehner once said that we should not be judged by what bills we pass, but by the laws we repeal. Harry Reid once said that the way to tell if you are a successful member of congress is by winning re-election. Not passing laws, debating treaties, or fighting for your state/district. It's can you keep your ass in the seat. There are many members on both sides that have done nothing legislatively, but have been in the congress for multiple terms.
Few members of the US Congress (house or Senate) are there to actually change anything. They talk big during the campaign, but once they are in office, they are ground down by the bureaucracy to being just another cog in the machine. Trouble with the Dems is that most of them have few to no ideas, but plenty of Ideals and butt hurt feels that everyone must pay something for and if you suggest they shouldn't then you are clearly a [insert form of bigot]. The problem with the Repubs is that some of them have plenty of ideas, but most of them suck. Other republicans are RINOs who are only there to either promote their latest book preying on conservative voters OR they are idealogs out to destroy as much of the federal government as they legally can making as much money as the can while doing it.
The problem I see is an infectious crippling disease commonly referred to as Identity politics. My group are the good people and your group are the evil people. How will we fix a particular problem? By not giving in to evil. RESIST!... no matter how stupid it is.... The Republicans were guilty of this during Obama's admin and the Democrats have gleefully taken up the torch during the Trump Admin.
The opposition use to be just be considered a opposing force of people who were just wrong. Now the opposition is made of monsters that must be destroyed and any who seek to "work across party lines" must also be destroyed as they are clearly traitors because they refuse to call Obama/Trump the second coming of Hitler!
