My more liberal friends haven’t liked Biden basically since the start. He was just the only option against Trump, whom they hate (a wonderful position our duopoly has put us all into). I will never be a fan of anyone that cheerleads for politicians though. It’s cringe to me. They work for us, not the other way around.
By "hardline dems" I don't mean "more liberal" or "more leftist", I mean the "You criticized the official party line? Behold, I will immediately misrepresent what you said and paint you as an enemy". They're actually preventing their own party from becoming more effective.
Biden managed to get a bunch of unions to endorse him for the elections, both due to negotiations and his policy. Given that Kamala was in his team, the only thing she needs is the will to declare that she will continue along Biden's lines.
If you genuinely think this didn't happen, you haven't been paying attention during the last month. Like there haven't been hundreds of people doing this shit:
