One of the things I wonder too is if the Republican party splits into multiple parties on the lines of what I discussed earlier is what vulnerabilities does that generate in traditional Democratic voting blocks? Democratic voting blocks tend to be less ideological and more identity-based (talking about models, not thought-process).
So, significant groups of African-American and Latino voters have a great deal in common with religious conservative groups on the right. Their opinions like up on a number of social issues and general economic policies - but their voting patterns are polar opposites. If the religious conservatives split off, are unencumbered by the white-identity politics of the rest of the Republican party, and are more amenable to the social welfare programs abhorred by the business elite I wonder what chunks of those demographics would be willing to move over.
Further, I wonder how deep the commitment to economic policy really is on the left when looking at a demographic of upwardly mobile, college-educated, white, Asian, and LGBT demographics if there is an aspect of the Republican party wholly committed to the business elite principles but unencumbered by the social and religious conservatism that translates as racist, homophobic, and anti-science to those groups.
I've been working through Rick Perlstein's trilogy on the rise of the modern Republican party starting with the Goldwater election, going through Nixon's election, and culminating with Reagan's election. Very interesting - he weaves a narrative that explains a great deal about how voting demographics shifted to where they are today. A lot of really interesting parallels with today's election. It's kind of taken me aback as I had been very committed to the idea of how this election was totally revolutionary and we hadn't seen anything like it. That's true in a number of ways but also some significant points of convergence. I highly recommend the books if it's a topic that interests you.
