President Obama HAD to have provided personal documents, such as birth certificate, before he was allowed to run for office, be it the Illinois senate or the U.S. presidency.
Mr. Obama has now provided the media his birth certificate after Donald Trump said that he would make public his financial records if Obama showed his birth certificate.
So, it is time for Mr. Trump to do as he said. Or, having gone bankrupt three or four times would cast doubt on what kind of job he will do balancing the budget and taking care of the public debt?
I think that going against Donald Trump and his "ridiculousness" is the best campaign strategy that Mr. Obama has.
