I think Tim Walz was very likely, simply because the centrists LOVED him. Don’t you remember him getting glowing recommendations from the likes of Nancy Pelosi and other centrists in the House? Idk how he pulled it off, but even though he fought for the wet dreams of many leftists he was beloved by the moderates who worked with him. I don’t think he would’ve faced much if any pushback from the ones who screwed us on Bernie.
