@snood,
The right got a LOT of mileage out of their three decade long "the Clintons are evil" story. They are VERY reluctant to drop the story because it has worked for them - their base has been trained to hate Hillary and there's no really comparable Dem figure in that sense. Pelosi is close (also female).
What Conway and other right wing voices are up to with their continuing concentration on Hillary is attempting to utilize the old story quite regardless of her absence from the political scene. They want to "position" (to use the advertising term meaning to tie together conceptually) the Dems and any new candidate with her.
It is also what Lash is up to regardless of how conscious or unconscious she is of this propaganda mechanism.
