The basic issue, as I see it, is that the Republicans can pander to divisive social issues (because they don't cost anything) and then give money away to business in the Name of Freedom™. Democrats can be liberal AF about social issues (because they don't cost anything) and then ask for a whole bunch of big government projects that cost a fuckton and interfere with big business. Spitballing, I'd say Democrats (the voters) care about health insurance, social welfare, global warming, reduced police militarization, cheaper college and cheaper housing. And I would say that for every one of those concerns there's a billion dollar lobbying machine hell-bent on the destruction of anyone who poses even a vague threat to them. Republicans? When there's money involved it's invariably takes the form of Give Tax Revenue To Crony Capitalists. Any democrat who actually runs on doing what democrats want is going to get creamed.
