What me worry?
Now that we know that people in the Whitehouse know that Joe Biden has dementia people are trying to make me worry because it is his finger on the button. They say can you imagine Biden running to the bunker to push the button? He can't go any faster than a slow shuffle, he'll trip and fall, it would make a great Charlie Chaplin film, but to be realistic it would probably be the 3 stooges who would be cast.
But this is just fear mongering. First, the Secret Service can run the football to Biden, and second, just because he is going to be too slow to enter the code in correctly Jill can do that for him, and she can also hold his hand as he pushes the button. So there, no worries.
