how am I wrong?
The constitution is only 27 pages. Read them.
It would be easier to say how you’re right.

You arw wrong saying the Senate would confirm Barack as vice president. That’s not how this works. Presidential and vice presidential candidates run together in an election.
You make it sound like Michelle gets elected president, then after election, chooses a vice president. That is not correct.
In order to be VP you must be eligible to be POTUS. Since he has already had 2 terms he is ineligible for VP. This question was raised when hillary first ran for POTUS and speculation was she would pick bill as her veep.
