In a book released on the eve of the 2016 election called “Asymmetric Politics,” political scientists Matthew Grossmann and David Hopkins argued that America’s political parties don’t just have different ideologies, but are really different kinds of organizations. “Republicans are organized around broad symbolic principles, whereas Democrats are a coalition of social groups with particular policy concerns,” the authors concluded.
I don’t want to treat that book as gospel, but it speaks to a certain understanding that has existed throughout my 17 years covering national politics. Democrats have been considered the party of Asian, black, gay, Jewish and Latino people, along with atheists, teachers, union members, etc. — in short, a coalition organized around a bunch of different identity groups. Meanwhile, Republicans have been thought of as the party of small government, low taxes, a strong national defense and “traditional” moral values — in short, a coalition based around a few core ideological principles.
That has always been a fairly simplistic view of the parties.
