I would love to see the 2020 numbers as well. This could be partially justified by saying that in 2016 he was establishing his political presence whereas now he is already widely known. But if he has reduced since 2020, then this is a sign of a loser, which I would love to see.

Edit: 2020 numbers:

June, after convention: 2

July: 0

August: 9

September: 15

October: 35

There has been a decline in August and September each time
