In the case of BHO, I don't think anyone thought fraud had been perpetrated to allow him to assume the office because had he lost we'd have been stuck with John McCain, who was in his time showing the first signs of what appeared to be dementia but was actually the resultant effects of his brain cancer, and the airhead Sarah Palin. When a MSM person interviews you and knows more about politics, the law, the Constitution, and how government works, might want to reconsider voting for what would be the most powerful woman on earth should McCain have won and stepped down due to health.
Also, the idea of fraud exposure may not have been broached for the same reason a Democrat in Congress , fed up with BHO's behavior in office, stated was the reason he wasn't impeached; no one wanted to have the charge of racism attached to their efforts to prosecute.
If fraud had been accused against BHO's campaign that's sure what would have come to the fore in defense.
In Philly, (Philadelphia), there were thugs outside voting stations carrying baseball bats and threatening people waiting to vote. Where were the cops?
That's what those people were asking.
If JB were allowed into office it would be BHO's third term. No doubt in my mind, BHO, HRC, Pelosi, Schumer, Feinstein, are all party to this election steal.
