Throw in some special lights and color editing work in Adobe Premier Pro to make her look her best and you have all the indicators that she is preparing for a run in 2020.

Based on what I saw over the last year, she either won’t be here in 2020 or they’re going to be photo shopping a wheelchair out of all her pictures ... if she’ll be able to keep from shaking enough for them to take one without it being a blur. As for personal appearances, they could just strap her to a heavy duty hand cart & roll her up on the stage & to the microphone - wouldn’t have to worry about her falling down that way.
Seriously, she’s an ill woman with problems that makeup, botox & the march of time will not make better. Bill also looks like a walking cadaver & that mouth hanging open like a fly catcher does not bode well for him lasting all that long, either. He’s been out of sight & might quiet lately, too.
Bill and Hillary Clinton are the penicillin-resistant syphilis of our political system.
