What can we expect from them Tuesday night?
Both have proven themselves as tough debaters, more than standing their ground in an assortment of debate formats.
    Also: there's humor. Clinton and Sanders may often be seen as serious candidates, but both have both let our their fair share of hearty laughs and "berns" respectively.
    There's also plenty of contrasts on delivery, but the only thing that matters is which style ends up delivering the votes.
