Even I am shocked that I would talk about President Trump and humility, but in this one regard he actually does exercise more humility than Pete Buttigieg.
President Trump has said more than once he has never felt the need to repent for anything. That raises questions about his salvation that I have explored in the past and also why I continue to think evangelicals who constantly cheer everything he does are doing his soul harm.
Pete Buttigieg is a practicing homosexual who willfully refuses to recognize Holy Scripture identifies that as a sin. He will not repent either. Not only that, but Buttigieg is also okay twisting scripture to justify abortion.
There is a big difference, however, between these two unrepentant sinners. Donald Trump does not lecture Christians about their faith and Buttigieg has made it a central part of his campaign.
So yes, in that regard, President Trump has more humility than Buttigieg.
