You're missing the salient point here - that her opposition to Trump was opportunistically picked up on as her ONLY beef with HRP.  This in and of itself should have been and was enough to have her removed from the position of minority caucus leader, at least.  But since 2012 she has consistently facilitated the opposing agenda with her legislative actions and in fact for at least two years has vocally and publicly indicated her desire to switch parties.  Until party leadership exists that will condemn this type of behavior, the party itself will be eaten alive from the inside.  Some would venture a guess that this is the design in place.
