As Vice President Kamala Harris, now the presumptive Democratic nominee, picks her running mate, some of her options may have problems within key coalitions of the Democratic Party. 

Sen. Mark Kelly (D-AZ) and Gov. Josh Shapiro (D-PA) are reportedly Harris’s two top picks, but parts of their past while in office may be unappealing to factions of the Left. Harris ran a progressive campaign during her 2020 run but has toned down some of her ideas while in the White House, and it is unclear how progressive of a campaign she plans to run this year.
