I thought that only applied UNTIL they were sworn in. After that, only congress could remove a president.
If Obama was never “legally” a president he never was. Impeachment is for presidents who have qualified for office.
However, we live in interesting times....
Read your Constitution carefully. Being sworn in is just one more requirement for becoming President, accomplishing that does not negate the others, such as getting the majority of the electoral votes, being 35 or older, having lived in the US for 14 or more years, and finally it being noon on January 20th, (or presumably after that date/time, if the other requirements, particularly the swearing of the oath of office have not yet been met. That means technically we are without a President when the swearing in is delayed past noon. This time, laying the other eligibility questions aside, we may have been nearly a day without a President, since the oath was not properly sworn .
Only if it was a valid oath with one who qualifies.
If I would have put my hand over the mouth of the president on Inauguration Day and swore the oath instead, it would not be binding, for I would not have met the qualifications. In that case, they would be merely words.
Congress would not have to impeach me, nor would I have to resign. In the case of Obama, if it is true that he does not qualify, he’s a pretender and the oath would have been null and void from the first word spoken.
The crisis would be that all he has done, all that he has signed, wouldn’t be legal, as he lacked the authority to do so. It makes me mad just thinking about it.
