Does the Addled Grumpy Guy Look Like He’s Leading or the Incumbent Having a Ball All Smiles Looking Confident?

Translate:

If president Trump were behind according to his internal polling, do you think he would look so loose and easy on the campaign trail, all smiles without showing any tension whatsoever? And if Sleepy Joe were ahead according to his internal polling, do you think he’d be so grumpy and defensive, shuffling around with his head down much of the time, probably wondering why he got into this?
