By naked corruption in Congress, I mean votes and favors being bought for cash, Senators and Reps on a regular cash payroll from large corporations and interests, and with liquor and prostitutes routinely on offer. What you are riled about is government abuse of the citizens, which is another kind of harm. The great modern remedy against that is the development of federal civil rights law, which was primarily (but not exclusively) the work of liberals in the 1960s and after.
Civil rights laws are the remedy for Federal corruption? You must be smoking an excess of that medical marijuana.
There’s not one thing you mentioned that’s not a regular fixture in Washington—though your quaint “liquor and prostitues” is a bit dated. Today’s Senator is more likely into young boys and hard drugs. Corruption has never been more naked, but many people still insist their politicians are clothed in only righteousness.
