I would note that the incorrect beliefs about Clinton reflect the Democratic establishment wisdom. The Republican establishment had the same issues. They believed Jeb was the best candidate and believed that Sanders was the dream candidate to run against. No and no. Jeb inspired nobody and at best could have squeaked by a bad opponent, while Sanders was actually formidable. Sanders was the only hope for the Democrats to keep the White House.

80% of political consultants need to get their asses canned. I would say they have no idea what they're doing, but that may not be true. They're all lawyers. It's like the MPAA/RIAA stuff. The organizations gain nothing, while the lawyers gain everything by convincing the organizations their services are valuable. No body of professionals jump from failure to failure like political consultants, all the while making bank.
