You're bothesidesing and rationalizing a complete lack of integrity.
AIPAC money, PAC money, and gold bar bribe takers are definitely corrupt and need to be in prison.
My belief is that to a large extent the art of politics is the art of bothsidesing and rationalizing away your integrity for common aims. And that when applied correctly, these common aims can be used to benefit the public. Look at systems where you can't bothesides (also known as finding common ground and compromising) or rationalize the integrity of other members (also known as acting in good faith). I suspect you will not find the results of these political bodies to have preferable results to the American Congress!
Honestly, I'm from NJ and I'm still shocked they actually charged Gold Bar Bob for what he did. He's so influential in NJ politics, I thought they'd let him get away with it like he did all the other bribes he's taken over the years. I guess literal gold bars from Egypt with obvious provenance was just too on the nose.
