Obviously there is always risk, a bad debate night can hurt you. Still, this is potentially a game changer, for Bernie. I assume both Trump and Sanders could hold their own against each other, but there would be a lot of interest (and high ratings) with such a debate.
Who would be the big loser? Baring a complete melt down by Sanders (which I think it unlikely), Hillary Clinton would be hurt if this proposed event went forward. Especially with the increased focus on her legal problems and corruption.

Trump says his past pro Clinton comments were insincere (Jimmy Kimmel responds back with a different, more salty way of describing Trump’s past comments and actions).
