The combination of Trump, Obama and the media insured that this week's story would be the birth certificate issue. Even though there isn't much of a story there. The birth certificate has been part of the much larger underlying issue which is the lack of transparency by the Obama Administration in even the simplest things. And that may not be a resolvable issue anymore.
It's not just that Obama has lied too many times. Most politicians lie or stretch the truth or hold back information. The problem is that the media and too many institutions have been willing to lie for him. Take a simple story like Obama Sr's time at Harvard.
