Longtime Clinton ally and Democratic strategist Paul Begala takes a similar view.
"Once more, the GOP runs the risk of appearing to be blinded by their partisanship," Begala said. "I have no idea if Hillary will run. But I know this: If she does this issue will not be a major stumbling block."
Begala drew historical comparison -- between Clinton now and then-Vice President George H.W. Bush heading into the 1988 presidential campaign.
"Remember Iran-Contra?" Begala asked. "Infinitely more damaging than Benghazi. The Reagan administration sold weapons to the ayatollah's regime in Tehran, then diverted some of the proceeds to the (Nicaraguan) Contras, then lied about it. The scandal paralyzed the Reagan administration for 18 months."
There were high-level resignations and criminal convictions, Begala recalled.
"There was a major joint congressional investigation, with highly publicized, televised hearings. There was a special prosecutor. It was one of the biggest scandals of the 20th century. And two years later, it had no impact on Vice President Bush's campaign."
