I mean that is the narrative right, we have to go with a centrist because it might scareee people to give them universal healthcare.
The reality is that in a lot of cases Biden is to the right of the majority of the US on issues. Take the Israeli genocide of Palestinians, it is extremely unpopular to support it right now among US voters (especially younger ones) but I am sure the media narrative is that oh we can’t say no to Israel, that would doom Biden for being too leftist.
