It is typical to expect campaigns to experience ups and downs. From a historical perspective, you wouldn't find one historian who could name a perfect campaign, but there are some that have made more mistakes than others.
A mere analysis of the Trump campaign would reveal several grave mistakes that could have and likely should have been avoided. Only time will tell how catastrophic those mistakes will prove to Mr. Trump's bid for the highest office in the land. However, one thing is certain, and that is the realization by either Mr. Trump or his top aides that something must change.
