Should McCain have ended this line with "Na Na Na Na Boo Boo"?

He might as well have come right out and said, "Barack Obama is a panzy, cuz he didn't serve in the war." Forgetting of course the fact that Obama was a child while Vietnam was going on. It's just another showing of double standards the republicans have. The party of "personal accountability" sure lacks that on all fronts. McCain used the same lipstick on a pig thing when talking about Hillary, but he is somehow disgusted when it was used against his campaign. He's a giant fake in a party of fakes. Americans need to see through his scare tactics and attempts to divert attention away from the discussion of any issues at all. HE CAN'T WIN ON ISSUES!! But people fall for this stuff, and it kills me. Americans need to wake up if they want to have any chance of improving where we are as a country.
