The term originated during the 2004 Presidential election when members of the US Navy Swift-Boat unit in which Sen. John Kerry had served came out in opposition to his campaign for the Presidency, and formed an organization entitled Swift Boat Veterans for Truth.
2008 Presidential Politics
Four years after the term was first used as a verb, it is now entrenched Democrat vernacular. Though, Democrats have decided to cling to their redefinition to be synonymous with lies and inneundo or smear and fear.  During the Democrat primaries, Barack Obama used the term when describing his opponents. “The cause of change in this country will not be deterred or sidetracked by the old ‘Swift boat’ politics. The cause of moving America forward demands that we defeat it.”  In light of the definition of the term, Obama's quote can be read as "The cause of [liberal] change in this country will not be deterred or sidetracked by [truth]. The cause of moving America forward demands that we defeat it [the truth]."
