Because Obama stated that his father was a British subject, not an American.
Even the phony BC says as much.
How do you know that is his father?
“How do you know that he is not a natural born citizen?”
“Because Obama stated that his father was a British subject, not an American.”
It’s clear public knowledge that Obama’s father was not a US citizen, so how come with 50 opportunities to knock Obama off the ballot on this ballot in each of the states, only a few crank lawsuits were tried and none was successful?
Perhaps the premise is wrong?
