Bernie Sanders is seen as the big winner of the Iowa caucus as he's tied with Buttigieg, who can't win big, non-white states. Trump's team was caught off guard, not having devised a strategy to confront the most electable candidate because they thought Joe Biden would be it.
America is feeling the Bern. I hope Trump enjoyed Michigan, Wisconsin and Pennsylvania because they're going to #FeelTheBern.
Any of these candidates will have a problem beating Trump. Unfortunately for Bernie, he has to deal with opposition research from Hillary as well as anything new the GOP dig up. He is viewed as an Independent. Just as Trump had the Never Trumpers there is an even bigger group of Never Bernies. Furthermore, it's a lose/lose situation with him, as if he wins, moderates will abandon him, if he loses, many of his supporters will abandon the DNC.
2020 Will be an election on Trump being the "I do as I say" anti-establishment and his 4 years of accomplishments vs others repeating the same 2016 "he will destroy America!"
People just don't accept it anymore. He is not an unknown quantity in terms of his results. What I would love to see is Trump be just as bold in his 2020 campaign promises and work to make them a reality in his second term.
Knowing his life ambition to win as often as he can, the world shouldn't expect anything less.
