Will Bernie Sanders run for president in 2020

He probably doesn't know yet either.  I'm sure he is considering it, and he is running for a Senate term that will end in 2024.  If he is doing well health-wise, I'm sure he will run.

I love Bernie, but come on... He will be in his late eighties if he completes his second term. That is nuts.

I'm not saying he will run or should run, but he doesn't have to run for 2 terms.  We elect a president for 4 years.

If Sanders doesn't run himself, then what is the probability that endorses anyone during the primary campaign?  There are certainly costs to doing an endorsement, as all of the candidates will want to suck up to him and pay lip service to his issues as long as he's officially "neutral".

If he endorses someone it will be Warren.  He has said that he wouldn't have run in 2016 if Warren was running, and recently at a West Virginia rally he called her one of the greatest senators this country has.
But I don't think Bernie has given up on becoming president.
