Clinton's people are ruthless, they destroyed people left and right in the 90s. When they went up against Obama, they started to try to smear him and they were shocked to be accused of being... RACISTS! The had to pull back from attacks, which along with lying is their standard strategy. So they had no real idea how to proceed and floundered. And got beaten.
With Warren, they will not let that happen. No racial aspect, no "beating up on a girl" aspect either. They'll go for the throat if they need to.
Your theory only works if the Chicago Mob truly doesn’t have a mutually assured destruction agreement with the Clintons.
(That’s assuming Lizzie is the Mob backed candidate)
