SARAH WANTED TO GIVE HER OWN CONCESSION SPEECH!
Sorry, honey, this is how it works.
When it's over and your team lost, it is the uncomfortable duty of the guy at the top of the ticket to man up, repress the myriad miserable feelings he has and give the gracious speech. (Sorry if anyone is offended by the use of the male pronoun here, but in American history so far, it's completely historically accurate.) McCain did that. He congratulated the winner, he noted the historical nature of the campaign, the thanked his supporters and he even went the extra mile, saying that any mistakes in the campaign belonged to him. People from all over the political spectrum have given him his props for what he did Tuesday night.
How could Sarah think that she deserved this one last moment in the spotlight?
One word: Narcissism.
Again, let me repeat. Damnit, Jim, I'm a mathematician, not a clinical psychologist, but I've found that in many of the cases of odd behavior displayed by Sarah Palin, either in public or whispered rumors from backstage, if you ask "Why would she do that?", one answer works a lot.
"Because it's all about her."
Why would she go nuts shopping? Why does she think the U.S.-Russia relationship revolves around Alaska? Why did she want to give a concession speech? Why doesn't she know any geography? Why were there Palin rallies late in the campaign where the signs didn't include McCain's name?
See answer above.
