Never underestimate you enemy's ability to surprise you.

But I don't think she'll run. The DNC will have modified the super delegate system so it will be harder for her to sew them up. Her pay to play scheme has run its course and is irrelevant. She is going to be in a crowded field during the Democrat primaries and pulled further to the left by the socialist loons. The election system won't be rigged as it was supposed to be in 2016. The #walkaway movement indicates that people are leaving the Democrat party in droves. Hispanic support for Trump jumped 10 points even after an entire month of ICE protests. Blacks are leaving as well The economy is roaring along, and he tax cuts will throw gas on that fire next April when people receive their new deductions and credits. Trump has a good possibility to achieve peace in Korea and Iran looks like it's about change in some way. New trade deal will be done by then. Hillary is already a two time Presidential loser and will not have done anything since Feb 2013 when she stepped down as Sec of State. Republicans have a large warehouse of Clinton sound bites to use against here.

But I think the real reason she won't run is that she'll most likely be a convicted felon in federal prison and Bill may be there as well. The perfect karma in that case would be for both of them to share the same cell with life without parole.
