The historical comparison photo is inadequate.
The guy we elected in 2008 has a giant deep visible scar on the left side of his head wraping a C shape around his ear which also has a scar which looks like the ear has been reattached.
I certainly don’t see that on the current guy. Maybe I am all wet—maybe the scar could be covered up with the hair growing out; I don’t think so.
That side of his head is avoided by photograpers. I did catch a view of it once and noticed scar tissue bunched up behind his left ear.
