...for a political comedy:
McCain is the candidate of "experience" - picks VP candidate with zero national political experience
McCain is the candidate of "national security" - picks VP candidate with zero national security experience
McCain puts his "country first" - picks VP candidate who was a member of an Alaskan secessionist party
McCain is the "responsible" candidate - picks VP candidate without doing basic political background research
McCain is the "maverick" - picks VP candidate after being bullied out of his first two choices by the evangelical Right
McCain is the anti-corruption candidate - picks VP candidate who ran Ted Stevens' 527 group and who hired a member of Team Abramoff
McCain is the anti-pork candidate - picks VP candidate who won $27 million in pork for her town of 6000 and fought for the "bridge to nowhere"
I feel like I'm taking crazy pills!
Unfortunately for comedy's sake, Palin is too young (and not Vietnamese), otherwise the perfect ending would be finding out she had been one of McCain's captors (had you heard he was a POW in Vietnam?) Feel free to add additional contradictions between McCain's rhetoric and his choice of Sarah Palin as VP in the comments.
When a candidate's relationship with the press moves beyond hostile questioning and into ridicule and satire, big chances are needed. Perhaps a third total restructuring of the McCain campaign is in the future!
