It isn't her place as the current vice president to publicly criticize her boss. I suspect she will be tougher on Bibi if elected- Biden has been in DC for 44 years
She has to thread a fine line campaigning- the choice is between the possible (Harris) and the evil knowable (trump)
and as a bernie supporter in the primaries he wasn't crewed- he just did not have enough votes. He was behind by June and HRC had clinched it already
The Biden admin has been, to my surprise,more progressive than any Dem admin since LBJ!
