They are all evil and corrupt. If they are not corrupt when they are trying to come in as Freshmen, the process of becoming freshmen corrupts them. They are all in the pocket of corporation money. They all get addicted to power. They all sell their souls to the machine.
There is no--absolutely no--useful difference between any of them, nor between either party. The Repubs say one thing to get elected and then do what their financial backers tell them to do. The Dems say one thing to get elected and then do what their financial backers tell them to. Thus, they all crow and point fingers at each other during elections, and then all enact the exact same policy (on the things that really matter) as the ones they were attacking during election.
They create mock-social-issues to get us arguing with each other, fostering Orwellian minutes-of-hate between the masses, against the masses, and use our misdirected anger to do business as usual.
Race wars. Gender wars. Trans-gender wars. Sexual persuasion wars. Generational wars. They foster and create distrust between the citizens so we never look at the puppeteers and get angry at them.
We're arguing right now about bathrooms. Bathrooms, folk... Where someone pees. We have the most systemic corrupt government in the history of the nation, and we're talking about where someone pees.
If the people woke up to the inherent corruption and systemic abuses set up in our gov't, they would be in the streets.
Obama, Chaney, Trump, Hillary... Each is just a different face for the same beast.
