My board is up to the challenge.
I'll add it to my reading list.
Without reading it, my reaction to the NV SSM-by-age data is probably more about party identification. Middle-aged Pubs are more likely to hold on to their party ID and let their social views evolve with the county. Younger voters are in the process of creating their sense of party ID, and will gravitate to the one that matches their views. So younger voters are more likely to select the GOP if they have views in line with the positions perceived as the core including opposition to SSM.
