Senator Amy Klobuchar of Minnesota; South Bend, Indiana Mayor Pete Buttigieg; Congressman Tim Ryan of Ohio.
These are the three Midwestern Democrats competing to promote the working class of the Midwest as Presidential candidates, and to close the gap of the working class vote lost by Hillary Clinton to Donald Trump in 2016.
All three are perceived as moderates, and it could be that one of these three Midwesterners might be the way to go for the Democratic Party, as they seek to win back the Presidency and the US Senate in 2020.
Klobuchar would be 60 in 2020, while Buttigieg would be 39, and Ryan would be 47. So each represents a difference in age over two decades.
