No.
Reagan was a good promoter and chose what to promote very well.
If Paul was into self promotion , why did he promote himself from one prison to another?
He had a more profitable job before he met Jesus on the highway, he left the career track , and took off on the tour of mendicant preaching.
Promoting Jesus is not a bad idea, if Jesus is the truth.
Otherwise , by Paul's own admission, it would be just a dumb thing to do.
