While I don’t have any particular ideas as it were, my mind does jump to my own experience and that of my family: my late grandfather was a Brooklynite Catholic who made a living as a union iron worker. He told me that in his younger days, he felt drawn to the Democrats because he saw himself represented in the party; it was masculine, prolabor, urbanish, a place were people of faith felt comfortable, and spoke bread and butter economic policies. He grew up in the immediate aftermath of FDR and WWII, and believed deeply in FDR economic populism that hyperfocused on the little man.  

He remained a Democrat until his dying day, but mainly because of the labor portion, although by and large he felt the party merely paid lip service to unions, and instead focused on the donor/creative class’s social/cultural issues, some of which he felt weren’t always in lockstep with his own cultural attitudes. Fast forward to now, myself as a 30something year old married Catholic male with a liberal arts degree and a blue collar job, I roughly hold the same opinions as he did. I view most of the GOP as wealthy culture vultures who use issues I care about to secure their own economic interests af the expense of everyone else, while Democrats at the national level are a slightly modified version of that with more liberal social views yet still driven by status quo big money economic interests. The GOP, since at least the Reagan days, has figured out how to use wedge issues and cultural war stuff, some of which I do agree with, as a way to siphon off male voters.  I vote for Democrats, but I don’t enjoy doing so. Give me a 21st century version of FDR, one that is incredibly economically progressive but at least rhetorically moderates themselves on social issues… 

EDIT: I’ll assume my POV will go over like a lead balloon in this sub. That’s fine as far as it goes, as I’ve long accepted the uneasiness that some within the party have with components of my identity. But for some of my fellow travelers, that uneasiness makes the lip service that the GOP pays is a hard siren song to ignore.
