Top Hillary advisor: She hasn't closed the door on 2020

CARLSON: She hasn’t foreclosed the possibility, I guess.

REINES: No, she has not.

CARLSON: That’s what I’m saying, too.

REINES: No.

CARLSON: So, I guess the question is: has the Democratic Party changed so much in the last three years that it would be possible for Hillary Clinton to get the nomination?
