I don't think anyone's unclear about the violations, but when our system of government is limited to 2 parties, and BOTH of them are bought and sold to various companies and departments with interest in violating that premise, the ideal is doomed.
What's the difference between ISIS and WMDs? Barack Obama and George W. Bush?
Did they ever figure out what Saddam did with the large stock of WMD that we know he had prior? Trucked off to Syria before the invasion? Where did it all go?
There's a small group of people making Republican politicians do crazy things (shutting down the government, blockading Obama, various social issues [gay marriage/abortion]), but by and large the Democrats and Republicans are the same.
