Now that Sen. Bernie Sanders (I-Vt.) is officially in the running for 2020, Meghan McCain is warning voters not to overlook his potential to win the election.

“The thing I will say about him is don’t underestimate him,” the “View” co-host said Tuesday, citing his 2016 sweep of New Hampshire and his success in taking nearly half of Iowa — the first two primary states, which will be important targets for candidates.

“This time there are no superdelegates to come against him at the convention like what happened before,” McCain added, referring to the Democratic National Committee’s rule change last year that stripped superdelegates of much of their power in deciding the party’s nominee.
