I think they did this to play against the left vs the right.
Biden doesn’t care about progressives, if they are against trump then those votes are already secured.
He is right wing and wants to appear more representable to conservatives to get their votes.
Its pure token symbolism but i bet it does have a noticeable effect in how the candidates are perceived.
How about being an authoritarian right winger who is funding a certain state to commit Holocaust 2.0
No hes not nearly as bad as Trump, Xi. Putin. But thats an incredible low bar.
If only Bernie got a chance.
