The Democrats need to get people excited for their policies somehow.
Wouldn't a good way to do that be to have compelling policies? Off the top of my head I'd think putting abortion protections/rights into explicit law would be a start. Frankly anything that is currently only legal on the basis of supreme court decisions also seems ripe for putting into legislative policy pushes to make into explicit legal protections, rather than relying on some decision that may be overturned by an arguably compromised court.
In that vein, expanding protections to the LGBT+ community would be another good piece to their policies. Also, on a larger note, more explicit and enthusiastic support of active unionization efforts that have been happening across different business sectors.
However, even beyond these, some that would apply more broadly might be policies to address housing and rent costs, as these affect basically everyone and anyone. Policies seeking to address housing/rent, education, and healthcare costs would altogether, I think, speak to a wider swath of the public than strictly focusing on the aforementioned concerns, but would also include them, e.g. combating redlining, undermining of public education, denial of medical services to pregnant women & trans people, etc.
I'll admit, maybe they have been pushing for some different parts of these (I'm aware of the Biden administration sort of trying to address college debt and getting screwed by the courts), but by and large I don't think I've seen a clear set of policies by the Democratic party of the United States to be excited for. Far more of it has appeared rather watered down and more along the lines of, "Well, we're not the Republicans at least!" instead of enthusiastically standing for something more constructive.
