Sky News host Chris Kenny says Joe Biden, at his latest appearance, has once again forgotten where he was and then attempts to pass his gaffe off “as some kind of joke”. Mr Biden had recently welcomed reporters to Delaware’s Kingswood Community Center, however he was actually at a different venue. “He is leading in the polls … (but) can he really run in November,” Mr Kenny said. Mr Kenny said there is continuing speculation at their convention in August, the Democrats “might even be looking to switch their candidate”.
