I havent read the article, but I disagree somewhat if thats the conclusion. Clintons dont particularly care about optics, and that usually gets them in hot water. She technically didnt send or receive classified info at hrod17@clintonemail.com, and said everything truthful to FBI. But the optics dont care. Someone else forwarded an improperly marked chain to her and she gets punished for saying she didnt send or receive classified info. Same thing with Clinton foundation. Same thing with Bill meeting Lynch on the tarmac. She gave speech to goldman sachs because she's from NY and an influential international leader. Nothing illegal. The optics weren't kind. She's corrupt and sold out. Same shit with Whitewater! It never ends. Its crazy how they survived this long.
I think there's a lot to criticize the clintons for and not all of it is baseless.
A large part of the reason these things don't sink them is once they're in office the Clintons tend to do a pretty good job.
Also the fact that despite how the optics look, the fact they never get in any actual trouble says volumes to people about the attacks on them. The fact people keep trying to make these optical problems into actual ones goes a long way toward helping them fight off any actual attacks, because it's just seen as more of the same bullshit.
