Are there any Mornons who truly believe in their hearts that Joseph Smith and Bringham Young were great men?

This is a legitimate question and one that is very relevent since two Mormons may be seeking the candidacy of President of the United States. People have a right to know and research who you would consider to be a great man as being indicative of your appointments. Obama has affinity to men like Rev. Wright and Van Jones, just as an example.
