If it's between Trump and Hillary, then Trump it is. That's only if I had to choose among the leading 2 candidates.
Not 100% sure about Trump, but Hillary as the Democrat nominee is almost confirmed as of now. Sanders is trailing by a big margin, and he has failed to garner significant support from the African Americans, LGBTs and the Hispanics. However, Trump's case is still not certain. There is still a chance that someone from the establishment camp could overtake him.
