John McCain would totally freakin' pwn and/or serve your favorite candidate in the finale.
If McCain were a giant oak tree, your favorite candidate would sound like a bundle of sticks falling in the forest when nobody's around to hear it compared to him.
Exhibit A: Hillary Clinton
aka "HRC", aka "Her Royal Clinton", aka "Right Triangle", aka "The Keeper of the Gates", aka "MC DLC", aka "VRWC Inc."
Exhibit B: Barack Obama
aka "The Quick Brown FOX", aka "N*Danger", Secret Service Codename: Mr. BOjangles
Exhibit C: John Edwards
aka "Lil' Millworker", aka "The Prince and the Pauper", aka "Southern Comfort"
Exhibit D: Dennis Kucinich
aka "M-Peach", aka "Mulder", aka "The Keebler"
NOTE: None of the other candidates bothered to show up for my YouTube talent search.
