I also think that Hillary is directly tied to this administration since she is the SoS. She has to answer to this administration and it’s record. Finally, if you look at her record as SoS, she has made the Middle East more unstable than ever before. She is a failure.
Also, I think that she's long-past seen her fifteen minutes as a "cool female renegade" within her league, and lacks the vibrance needed to fire up a NEW crop of disgruntled PUMAs or pretty-people young liberal women.
Anymore, she (sadly) presents as a long-in-the-tooth (figuratively, mainly,) unengaged, bloated and perpetually half-in-the-bag, bumbling (like you said,) bowling ball.
She just kinda awkwardly wobbles down the lane and gutters out...in a long-empty bowling alley.
