Openly gay Democratic presidential hopeful Pete Buttigieg was under fierce attack Thursday night in the sixth Democratic debate and, by the end of the evening, there was some data suggesting he had suffered some injury to his effort to convince voters he is a candidate who listens to the little guy and is electable. And the three-hour event in Los Angeles brought more reference to LGBT issues than the previous five debates. Most of the incoming hits at Buttigieg were fired off by U.S. Senator Elizabeth Warren, one of the Democratic field’s most progressive candidates, but Buttigieg also had to fend off significant attacks by one of the field’s moderate challengers, U.S. Senator Amy Klobuchar.
