Our investigative journalists did nothing to correct Obama's bio in his publisher's guide of 1991 that stated he was born in Kenya. Back in the old days, that gave a young author a lot of gravitas. It was corrected in 2007, around the time he decided to run for president. That doesn't mean he was born in Kenya; just that it was a convenient lie that came back to bite him. A bit like Elizabeth Warren's heritage as an American Indian. Some glamor for her being a minority--which she wasn't.
But our sharp eyed press did discover Mitt Romney's great-grandfather was a polygamist who had fled to Mexico to protect his family, although they said little about Obama's polygamist father who had fled his family responsibilities leaving a pregnant teenager and gone back to Africa.
Someone, or maybe it was social media, or maybe "real" press corps, was outraged that the Romney's dog traveled in a carrier outside of the car many years ago. That was an important story in the 2012 election.
Let's make America great again with the kind of in depth discovery we've come to expect from our media giants. NOT.
