I believe that if Barack Obama did not make it for the presidential elections this time round, he will very likely just make it 4 years later if he tries again, at the older age of 51.
I hope he wins this round.
But can you just imagine if the whole world pins their hopes on him because he seems like such a trustworthy politician with all his smooth speeches and charm, and then when he finally gains presidential rule, he turns out to be no better than Mr George Bush?
It will be a letdown, but it won't be a surprise either.
