You better look around on this thread. You should look in the mirror of the guy who can't figure it out. And about 'the de facto officer doctrine,' I gave you a pretty detailed paragraph in post 142 why you are wrong.
In post 142, you made an assertion. Assertions are not proof.
Saying Obama was accused of wrongdoing before taking office doesn’t change the fact that he has been recognized by every government institution and every member of Congress as President since 20 Jan 2009. So your assertion is wrong.
