I think that Congress can be saved, but if it will not act in the best interests of the country, we may have to revise the Constitution to eliminate the legislative branch. That will leave the Federal government with an executive branch and a judicial branch. Laws, treaties and confirmations would be subject to approval of the people by referendum. The Founding Fathers gave us a representative democracy partly because the technology was lacking then to permit a large-scale direct democracy. Now we have that technology in the internet. Direct democracy will require an informed electorate, willing and able to participate in government on a daily and weekly basis. It will require laws that are understandable by the average voter, and it will save money by eliminating a costly branch of government. Let’s insist that Congress clean up its act or we the voters will do it for them.
Technically, the US is a republic, a representational democracy with protections for minorities. Most people shorten that to a democracy, which is majority rule. Both definitions are true when the Democrats are in the majority. When the Republicans are the majority, the democracy definition still holds true. However, when in the minority, the Republicans still try to rule under the definition of a republic, but they then try to eliminate protections for the majority.
