No, I don't believe so. I'm talking about the people who convinced them that culture wars were the right way to do battle with a conservative opponent despite that being automatically an uphill battle. The dem leadership focused on issues that polled well with a small group of loud people on a crusade, and largely ignored bread & butter issues that resonate with people less politically inclined. But centrist votes are counted just the same as partisan ones, and more plentiful.
Which dem leadership? The only crusade I remember was Kamala Harris going on a national tour with Liz Cheney and brightly signaling her rightward shift. Somehow, "Republicans for Kamala" failed to save her campaign in the swing-states.
