A term for differing schools of political campaign theory, originated by ABCNEWS' The Note internet report referring to the Iowa caucuses of January 2004. "Mo" refers to momentum, or the last-miute media impact of a candidacy, whereas "O" refers to organization, the ground troops of a campaign fomenting a result.

For interest, "Mo" triumphed in Iowa 2004, as the insurgent campaigns of John Kerry and John Edwards soundly defeated the old frontrunners Howard Dean and Dick Gephardt.
"So this will be a contest of mo versus o."
