Can't agree with you on this. President Ronald Reagan spoke at at least one rodeo; it is a great tradition.

There are reasons to prefer President Trump over Governor DeSantis. For one thing DeSantis may be too conservative for some Republicans.
But going to a rodeo is not a strong argument against a politician.
Reagan WAS the President. Ron is not. As you could see by watching this it did not go over with hoots and hollers. Trying to be like Reagan is also a bad idea because this Ron is certainly not Reagan.
