I hate to write it, but the press describes this district as educated and affluent and offended by Trump. So, for whatever reason, the voters gave Romney a landslide win in this district and Trump barely squeaked by. So these voters are not Trump’s assumed base of white working class voters. Of course, I think Trump’s base is a bit broader than that. Trump did win college educated voters, not by much, but he did win that group and he was not expected to do so.
One hopes they've come around based on his performance since his inauguration.
