@Moldova- I know what you mean. I also think that the halo effect was attributed to Obama as well. People felt that he had superior speaking skills and enjoyed his speeches. Many Americans attributed the halo effect with Obama because they assumed that since he spoke well he must be able to do everything else well too.
This led to much disappointment because none of the attributes that people gave Obama actually suited him. We get disappointed with the halo effect because we are expecting perfection which is really unattainable.
Obama had no leadership experience and only served part of his only term as a senator. However, this did not stop people from experiencing the halo effect with Obama.
