Ah, a cynic I can sympathise with the cynical view, but it's really not a wise place to live. It leads to apathy, and that plays right into Putin's hands.
This defense of a lying President by those who claim 'both sides do it' is no defense.
I don't know if you have noticed, but there are only two parties with caucuses large enough in all the legislatures across the land that can affect change, they are the GOP and the DNC.
Pick one, and if the party you pick isn't behaving to your standards, do everything in your power to put it right.
That is all you can do, because no third party can gain traction in America because of the "Republic' as designed. In a parliamentary system, which consists of a coalition of different parties, you'd have a chance.
I understand the things that have been wrong in the past regarding the Democratic party, but compared to the right, they are choir boys and girls.
