I have ignored the rest of this thread, but here is my take when you asked what would you have the Dems do?:
1) Expand their coalition beyond the base. Some of this IMO is getting over the labeling issues and perceived overreaching ideology (I'm not saying abandon all civil rights efforts). I live in an area with a lot of mixed marriages (and gay marriages) and no husband or wife wants their spouse or child, or friends for that matter, to be put behind because they are not in a preferred heritage or class that for example, some school administrators for example, select over wine and cheese. Not to mention there is voter backlash to perceived "wokeness", anti-merit claims (which causes minority resentment), and the promoting of mandatory ideological conformity and overreaching on speech and everyday interaction. A lot of this seems so pretentious and formulated as to be counterproductive, as to seem essentially superficial "check-the-box" diversity efforts rather than substantive change. Changing the phrase master bedroom to primary bedroom doesn't do anything about police stops of black youths that go wrong. But right now the Democrats (and academics) are turning off large groups of people.
You guys are even getting crap on Netflix shows. I admit this means not avoiding hard topics or creating an echo chamber to only talk to voters who already agree with you.
2) Focus on economic anxietiy: cost of living fair game and jobs. And focus on that. Why the heck were Democrats afraid to discuss Biden's move to revitalize U.S. semiconductor manufacturing (which Trump continues) , with over $25 billion in incentives awarded and the elimination of government land use regulation which I might add resulted in thousands of jobs and almost a $ Trillion in private investments? Stop selling what is wrong with business. Most voters work for businesses, not the goverment. Avoid tariffs (unions and blue collar are pro protection, and almost everyone loves tariffs on Russia and China) and class warfare (many people have aspirations for being rich one day, and don't want some Sanders' type policies to take that all away). Lose the ideological fixations. This is somewhat critical as a record number of Democratic registered voters didn't vote in th the last election. Exactly why the Harris campaign's message, with all its spending and media support, didn't connect with so many vital base voters is a complex, not to mention that swing voters or ani-Trump GOP voters (e.g., Haley republicans) didn't break their way. As for the base, the Dems had a diverse ticket, mostly espoused all the correct progressive views, and presented a rosy picture of recovery of the post-C-19 economy. But a lot fhe the base didn't think the economy was rosy, and still don't. Young voters are especially pessimistic.
3) Change the message on immigration to be more moderate and consistent: This might apply to the GOP as well. Polls have shown people want the borders shut and some form off amnesty to those who have been here for some time. Immigration killed the Dems in 2024.
4) Stop arguing Republican issues: avoid law and order, tariffs (lot of the country wants protectionist policies), TRANs athletes (how many are there?), etc. Get out of the culture wars - like or not, and I don't, the country has moved conservative on social issues ever since 9/11. The GOP is vulnerable on the economy. Stay there.
5) Move on beyond Trump. He isn't running. Focus on the GOP ticket. By 2028 the voters may be looking for
someone with emotional and intellectual maturity and not another round of divisive political rhetoric. And avoid Biden betrayals, and avoiding having a battle tested campaigner be the candidate. No super-delegates, burying candidate worts. etc.
Listen, you asked...
