It is easy to understand why.
The present day political process is ultimately about money and power.
Due to the disparagment and dismissal of our Constitution's by politicians, judges, and too many citizens, we are beginning to live in a democracy, authoritarian in it's tyrannical decisions.
Also, these same anti-liberty decisions are followed up with the disbursement of millions of dollars to the group that has the majority votes, whether democrat or republican.
And this is different from the past how?
The Founding Fathers were keenly aware of this problem which is why they wrote the Constitution in such a way that it would "pit competing ambitions against each other". It is nothing new.
