I think Hillary’s preference was to be reoriented to the center for a general election by now. She is being forced farther left in order to respond to the traction that Bernie Sanders has received.
Ideally, she wanted to cleanly sweep everything so that her nomination (guaranteed by super delegates) would have the patina of authenticity backed up by legitimate popular wins in swing states.
Since Bernie upset her in Michigan, her plans have gone awry. One thing for sure, I think she will stop at nothing to prevent a repeat of 2008 when Obama stole (in her mind) her entitlement to the nomination.
Hillary and her rat pack already have their cheating cards in place to steal the election. The GOP establishment will never let Cruz get rid of the IRS. The IRS is the Dems and Repubs fear control of the people. The GOPe will see to it that Clinton wins if only for this reason.
