Ed at Gin and Tacos, explaining the inexplicable:
The final group is where things get ugly. Converse labeled them NIC: No Issue Content. These people have a party they identify with but cannot explain what it stands for. They have opinion, but opinions with “no shred of policy significance whatever.” They like individual candidates based on their personal attributes and they have no substantive understanding of any policy issue, so the ideas they appear to support can appear quite random and perplexing to the observer in aggregate.
Re-read that last sentence. Does that sound familiar?
The most incredible thing about the Trump campaign from an academic / political science perspective is that we have the rare opportunity to observe a major party campaign with no ideological content whatsoever. There is no coherence to anything about Trump, policy-wise, and this reflects his supporters’ similar lack of meaningful ideology. On what rare occasions that he does put forth an actual idea it 1) makes no sense and 2) bears no identifiable relationship to any other idea he mentioned before or since. It is the definition of random. His appeal, in the eyes of his supporters, is that he is Tough or Bold or some personal characteristic that one could only get from watching and listening to Trump if one does not understand what anything in the realm of ideas in American politics actually means. Moreover, one must explicitly not care what any of it means.
