Your honest opinion, is Obama American born?

Since almost all recent candidates for presidency have been required to provide their long form birth certificate to prove they were eligible to preform their duties, it would have been nice if the current president had done so AND not spent so much to try and hide his information. Even his wife has stated his homeland is Kenya, now what does this mean? Why hide it along with other information if he has nothing to hide? Why leave the questions and not PROVE you were born in the US that is if in fact you were?
