Obama is a Natural Born Citizen?

[1]

What if Obama is actually a natural born citizen? Why the cover-up?

Perhaps Frank Marshal Davis played a more important role in Obama's story.
Perhaps Uncle Frank is actually Obama's Real Father [2].

Obama's efforts to conceal his birth certificate along with assurances that he is constitutionally able serve as president make sense.

• I find it hard to believe, no matter how partisan, that an elected official would lie about eligibility.
   
• The cover-up would expose Obama as the fraud he is considered, therefore, concealment is tantamount.
   
• If Obama was accepted into Occidental and Harvard based on the premise of him being a foreign national, that
  would be additional instances of fraud. [Harvard needs more of this attention -- thanks E Warren]
   
• Circling back to eligibility, did Obama renounce his US Citizenship? When he was adopted and became Barry Soetoro,
  was his citizenship changed? When he traveled to Afghanistan, did he have to claim that he was not a US Citizen?
   
• Barry Soetoro -- did he ever legally change his name or did he just assume his original name as an alias?
  This would be yet another example of fraudulent activity.
   

If this was revealed as true, how much of a game-changer would this be?
Would the people care about his lies and fraudulent behavior?
