At best a crackpot one with no serious support from contemporary leaders such as Churchill, or historians since then AFAIK. Putting the war in the Pacific aside, I think you can place much of the blame for WWII on the election of an extremist in Germany, and that had little to do with any alleged "boredom" in the electorate. A fairly decent case may be made for "anger", "disillusion", "jealousy" and "resentment" though, and I suppose you could make a case for those also being important factors in the 2016 US election.
