Longtime Republican focus group and pollster Frank Luntz lit into Donald Trump's awful presidential debate showing to Piers Morgan on his Uncensored streaming program. Early in the debate, Luntz was criticizing Kamala Harris' facial expressions, which was sexist and he was rebuked on Xitter about it. If she wants to win, Harris needs to train her face not to respond.It feeds into a female stereotype and, more importantly, risks offending undecided voters.
