Twenty minutes into the presidential debate came a simple question. The answers were anything but.

After reading out some statistics from the deadly Hawaii wildfires, they played a clip from a member of the Young Americans for Freedom, a conservative youth activist organisation, who said climate was the number one issue for young people.

Asked to raise their hand if they thought mankind was to blame, not one went up. And only one candidate said climate change was real in the short discussion that followed.

Florida Governor Ron DeSantis said it was childish to ask for a show of hands and instead laid into Joe Biden for the president’s response to Hawaii.
