I think this deserves a separate post.
Manafort was never anything other than a slimy political insider, but Trump needed the services of that type of person during the primaries when it looked like Ted Cruz was going to steal the nomination through sneaky delegate shenanigans. Hiring Manafort was an excellent idea at the time. Trump needed slime to fight against slime. Manafort was then replaced by Steven Bannon for the next stage of the campaign which needed a media expert and not a slimy political insider.
It seems to me that Manafort is in big trouble, because the MSM is out to punish everyone who helped Trump rise to power, and all of Manafort’s sliminess is going to bite him. Meanwhile, the equal or even greater sliminess of other political insider and lobbyist types from both parties will continue to be ignored, because they weren’t involved with Trump.
