Here’s why Shy Trumpster may have an effect on the polls even though the Bradley Effect didn’t work for Obama. If you’re talking to a black person on the phone, you might be more shy to say you’re against Obama. But doubtful for anyone else. And obviously the chance an obvious black voice was polling was slim.
But with Trump, you might be shy to say you support him if a WOMAN is polling you. Women are probably the majority of the people doing the polls.
