Hopefully Trump will not be able to bankrupt the government in 4 years. Filibuster in the Senate is an option for 2 years and maybe there will be some shift in 2018.
The bad news is that the filibuster is very likely to be done away with because it is the only thing stopping the Republicans from doing literally anything they want. And the map in 2018 doesn't look good for the Democrats.
No, they won't do away with the filibuster. Filibusters are theater - they allow Senators in the majority party to kill a bill and support it at the same time. Conversely, they allow people in the minority party to insure a bill passes and vote against it.
We've seen this over and over from Senators in both parties. The filibuster is dumb as a procedural tool, but as a political tool it's invaluable for Senators who want to make a career out of the Senate.
