Senator (and former presidential candidate) John Kerry (D-MA) warned in late March that former Massachusetts governor (and current presidential candidate) Mitt Romney (R-MA) will "swiftboat" President (and current presidential candidate) Barack Obama (D-IL) in the coming election campaign.
In doing so, Kerry relies on his political friends and supporters having talked (conned) enough people into believing his (and the Left's) definition of that term as, in effect, a smear campaign. (They've certainly spent a large propaganda effort on this.) The trouble with that is that there are too many of us around who remember the original instance of "swiftboating" as a rather accurate attack on a deceptive and unfit candidate. Kerry might have considered the attack unfair, but he could not truthfully believe it to be false as the main media claim.
Kerry has claimed his military and discharge records would demonstrate that the charges made by the Swift Boat Veterans for Truth were untrue. It makes me wonder why Kerry hasn't released his records, as he promised he would. (Actually, no it doesn't.)
Update: Others have noticed, as well.
That's a reference to the Swift Boat Veterans for Truth, the group that in 2004 deflated John Kerry's claims of Vietnam heroics.
Unlike Kerry's boasts, though, Obama's are drawing derision even from fellow left-liberals. Washington Post columnist Dana Milbank writes that Obama's "nonstop campaigning is looking, well, sleazy and his ad suggesting that Mitt Romney wouldn't have killed Osama bin Laden is just the beginning of it."
