Joe, The Lesser

 In case you missed it....from that weekend G-20 meeting.  The guy on the far left (red circle) is Joe Biden.

If you were Bill Clinton, Barak Obama, or Donald Trump....you were typically in the middle, and normally on the second row.  

It's almost like he showed up....got into the photo by accident, and then left.  

In history, we have those occasions when historians note people, as 'the greater', or 'the lesser'.  I think in this case....it's appropriate to note President Biden on the 'lesser' side.
