From the article you linked:
While 71 percent of Republican voters supported the ban
I don't believe any other Republican has supported the ban, so that the issue is an overwhelming win for Trump in the Republican Party.
Yup, agreed it's a win for him in the Republican party.
I'm curious about your thoughts on my piece in Salon analyzing Trump's emotional appeal using rationality-informed ideas. My primary aim is using the Trump hook to get readers to consider the broader role of Systems 1 and 2 in politics, the backfire effect, wishful thinking, emotional intelligence, etc.
