How will these figures be viewed in 2070?

Reagan will be viewed more for his role in the end of the cold war than really his economic policies by then. Really every President from 1945-1991 will be viewed in the context of the cold war more than any domestic policies they passed(with maybe the exception of LBJ due to civil rights and Nixon due to being the first president to resign due to scandal).

Hillary will be remembered as the wife of a former President and the first female to be nominated for President

Bernie will be forgotten given unlike WJB/Goldwater he wasn't even nominated

Obama will be remembered as the first African American President but other than that I believe the time period of 2008-2020 at the very least will be known as the age of populism and both Obama and Trump will be grouped in for that era

Biden will either be known as the President who ended the age of populism if he is successful or if he  fails will go down similar to what Taft was in the progressive era.

I actually think its possible that Obama and Trump could be viewed together in a similar way TR and Wilson are . Just like that era was called the Progressive Era, I think their era could be called the age of populism or the age of outsiders but the difference is while the progressive era is considered a success this era will be considered a failure.

Keep in mind that while Obama and Trump are viewed as very different today and both despise what each other stand for so did Teddy and Wilson. Teddy absolutely hated Wilson and attacked him a lot during his presidency and in extremely harsh terms too. Their approaches were extremely different too, almost as stark as Obama's and Trump's:

Teddy: His foreign policy was based more or less on nationalism and his desire in a way to create an American empire and basically tried to get his agenda passed through the use of the bully pulpit.

Wilson: His foreign policy was more based on a vision of more global cooperation, and governed in a very intellectual and professorial manner.
