Ah, yes. Joe (Finger to the Wind) Biden. But yes, he has always been a moderate. He was the most conservative Dem running.
He’s governing much more to the left now than he’s ever been though because he is mirroring the changes in his party. The party has gone quite a bit to the Left since 2016. Biden’s always been the ultimate Centrist. That’s what a Centrist does – he moves left when his party moves left and he moves right when the party goes in that direction.
The party has been split during the Trump years between the Hillary-Biden wing and the Bernie-Squad wing, with a lot of in-betweens. The two factions hate each other so much they nearly want to kill each other.
However, they seem to have buried their differences for now and rallied round Biden for the purpose of ending Trump, who they feared and hated nearly as much as a vampire. In fact most saw him as just that – a bloodsucking entity so anathema that you want to hold up a literal cross to keep it at bay.
The US Left actually hates Biden, but they tend to be largely outside of Democratic Party circles. They especially despise him on foreign policy, where he has simply continued Trumpism.
