This is exactly why the Constitution must be adhered to in spirit as well as by the letter - there will always be corruption and bribes and blackmailed politicians.
We the People should DEMAND the Constitution and the rule of law be strickly followed. That is the starting point to solving many of our problems.
As far as corruption - unless and until this country makes God Almighty their Lord again through Jesus Christ, all three branches of the Federal government and the Courts will remain unscrupulous.
We can scream all we want, and it will do no good. The solution is to restore federalism.
