A Sanders government wouldn't be too bad... Not as good as a Trump government, but not bad. Reason being, he won't have control of congress, so won't be able to achieve his socialist aims. And I don't see him being as heavy on the executive orders as Obama was. Also, his foreign policy ideas are not terrible.
Trump called bernie a communist. So to many of the blind repubs on getbig, bernie will be a communist from this point fwd.
Personally, I cannot see Bernie OR sanders winning this. I think bloomberg is absolutely going to jump into the race now. Trump is calling Cruz a p*ssy and laughing he could shoot someone on 5th avenue. Bernie is an admitted socialist. hilary is about to be indicted and is old, fattening up, and looking impotent. The repub bunch looks inept - "Robio"? Cruz cheating and lying obvious. Christie is super liberal. Jeb is just wimpy. No "men" in the group except Trump, who is promising things (wall, import tariffs) and other things which he legally cannot do. He's emotionally out-of-control and doesn't understand presidential powers.
I think bloomy enters the race very very soon. There are no really good canddiates in this race - all have dealbreaker flaws that we're not admitting because there are no good alternatives in the race.
