Some interesting numbers in this Harvard Institute of Politics poll of 18-29 year olds. This in particular jumped out:
Trump approval/disapproval: 29/68 (all)
Pelosi approval/disapproval: 36/61 (all); 42/57 (likely voters)
Congressional Democrats approval/disapproval: 47/51 (all); 53/46 (likely voters
Congressional Republican approval/disapproval: 29/68 (all)
Trump and the Republicans numbers are basically the same across the board.
When asked about the Democratic primary, Bernie leads with 29% across the board, Biden is second at 18% for all and 21% for likely. I suspect this mostly has to do with name recognition, still. Hopefully it changes.
