Joe Scarborough: Anybody Who Underestimates Sanders Does So at Their Own Peril

EXCERPT:

ELROD: “He’s now performing anywhere from 16-20 percent in Iowa. In fact, that’s going to be an interesting factor to watch. How does Bernie -- does he pick votes, does he pick up steam, or does he stay as a front-runner but not doing as well as he did in the early states in 2016? That’s going to be a very interesting thing to watch."
SCARBOROUGH: “And I agree, Mika, that anybody who underestimates Bernie Sanders does so at their own peril."
