I'd call that a very strange take, considering Dems support for arming genocide just lost them a rather important election. Not a popular view among their base.
Maybe we could try electing people who are ambitious - but for the good of the country and the planet, rather than themselves and their billionaire owners.
Can you support that claim with anything? It looks more like they lost because of various factors: Republicans have zero connection to truth and news outlets parroting those bullshit Republican talking points whilst hammering actual facts and figures from Democrats; the USA would rather elect just about anyone other than a qualified woman; the failure of the Biden administration to deal with Trump (et al) for their various crimes; and various Republican shenanigans to do with gerrymandering, postal votes, etc.
Sure, some people may have refused to vote Democrat and cited "support for arming Israel's genocide" as their reason but those people are absolute morons if they believed for one second that Trump wasn't going to do exactly the same and more (since he'd given every sign he was a full-on Netanyahu stan.)
