“You definitely have the potential to have a convention where there are multiple candidates with multiple groups of delegates and there’s a fight at the convention,” Sirota said during an interview on “Rising.”

“So I’m not necessarily saying that’s going to happen but it’s not always a winner take all system,” he continued.

Sirota added Sanders is already well-positioned in the crowded Democratic field.

“Sanders being so well-known, his agenda being so clear, and his agenda being distinct from so many of the other candidates puts him in a very, very good position ... to win the nomination,” he told Hill.TV.
