I love Bernie, as y’all know, but I largely agree with the points a lot of posters here make about identifying as a socialist when trying to win national, and local as well in many cases, office. I think a lot of average Americans and working class folks like progressive and even socialist policy when asked about specifics. The label mucks it up.
The good thing is, we have a deep bench of Democratic candidates who I think are well positioned to run as progressive populists while not not being affiliated with socialism: Andy Beshear, Gretchen Whitmer, Tim Walz, and J.B. Pritzker all have solid, progressive bonafides and could credibly run as populists.
The competition in 2028 is going to be between these kind of candidates and the more centrist candidates like Buttigieg, Shapiro, and Newsom.
