Fox News senior political analyst Brit Hume suggested that 2020 Democratic front-runner Joe Biden is suffering from creeping senility.

Responding to Fox News host Tucker Carlson’s assessment that Biden, 76, seemingly doesn’t even want to be president, Hume said, “I think he’s always wanted to be president. He has tried it before repeatedly, right? Hasn’t worked out. I think now perhaps he thinks it’s his turn.” Hume went on to say that Biden’s gaffe-prone style has been a problem for him in the past, but that his more recent blunders likely indicate something more serious.
