I doubt it. A 10-year-old could join two pics smoother than that. And it would be pretty stupid to do since there must be other photos besides one. It’ probably a street or walkway. You can see the same thing in the Portland (?) pic from a few days ago. Remember, STL is a fairly big city and there are a lot of black folks there. Having 100k at a rally for him is not beyond belief.
There are more than 100,000 blacks just in St. Louis City alone. Add to that the white libs in St. Louis County, the dumb old lifelong Dems, and the ditzy celebrity-worshipers, and the crowd is understandable.
However, I here in south St. Louis County had better things to do with my time, even though the Arch is only 20 minutes away.
After a couple of hours there going in the streets it must look and smell like a sewer ugh.
