Did Obama Peak Too Soon?

I found this interesting questioning article questioning whether Sen. Barack Obama peaked too soon.

It's possible that he did peak too soon, but I don't really think that's Obama's problem right now. Within his campaign, they've made some strategic blunders based on the fact that Obama's been able to raise all of this money, and capture the hearts and minds of many of our young people. Simply, I think the campaign became arrogant, and never imagined the Sarah Palin factor in this campaign.

I now think that Obama will win or lose this campaign based on his performances in the debates. He'll really need to sharpen his responses and be specific, though, because Sen. John McCain is very decisive and to the point when he responds to questions. Obama will need to go to the Hillary Clinton School of Debate Performance, and prove to the American Public that he can be a decisive leader.
