Unlike the exchanges of civility and common courtesy we expect in our routine, everyday lives, politics should be viewed as a parallel to boxing: a bloodsport where recognition of the opponent's weakness is an opportunity to be completey taken advantage of. (You can be civil and honorable once you're in office.)
The McCain camp--specifically the candidate himself and his wife (although the candidate may not be speaking for the campaign)--gave repeated assurances of a clean, issue-based campaign. It seems now that if they were ever sincere about a clean campaigning pledge, it was conditioned on McCain not being behind in the polls. Oops.
So, they want to play rough? They want to let their desperation lead them to questioning Obama's patriotism; to compare him to likes of Britney Spears and Paris Hilton, etc.? Ok. Bring it on. Obama people: it's time to POUNCE. Hard. Swiftly. And decisively. Don't go all Pelosi on us.
Speaking of which...
