The problem with these "Obama Scandals" is that the GOP is politicizing them before they have any real evidence Obama's actually at fault. They come off as desperate to pin something on him(IRS), hypocritical(NSA) or with Benghazi, opportunistic in the face of tragedy.
Yes, what the IRS was/is doing is suspect and needs to be investigated.
Yes, Benghazi needs to be explained.
Yes, the NSA is out of control.
What Republicans need to do is actually investigate, and if something is linked to Obama/Hillary, then they can politicize it.
Benghazi seems like something that might actually really damage Obama or Clinton, but the GOP has turned it into a partisan witch-hunt. Now if they actually find any wrongdoing, it will come off as politicized.
The NSA has been out of control before the Obama Presidency.
