Unless he is 99.99% absolutely confident that he could run 3rd party and garner enough votes so that neither party had the majority, he would be a complete fool...unless his intent all along has been to hand Hillary the keys to the front door of the White House.
It is nearly impossible for a 3rd party in these days to win.
Why would you say that?
Perot didn't have the internet. He was at the mercy of the liberal MSM at the time. And today's MSM is infinitely more out in the open about their bias today.
Today's social media Facebook and Twitter, plus DRUDGE has changed all the rules.
A 3rd party could win...if that candidate comes from the GOP. Don't think Bernie Sanders could do it as an INDY.
IMO, he's holding the Clinton regime hostage for a nice incentive to drop the idea. About $10 Million should do it.
