The political landscape has shifted since the revelations about a series of scandals and the tumult surrounding the National Security Agency spying activities. Hillary Clinton, once thought to be in the catbird seat, now faces some big challenges.

She better get some good comebacks:

“Well, it wasn’t really the 3:00 a.m. call I talked about in 2008. I was more like 10 p.m.”

” Okay, so maybe it did matter.”

“Sure, there’s Benghazi, but you can’t pin all the other scandals on me.”

“I might not have spoken out about the NSA data mining when I was in office, but I really meant to.”

“When I said ‘Russian reset,’ I never said it would be better.”

“I did warn you all in 2008 Obama was not up for the job.”

“Late on gay marriage? Well, at least I was early on support for the Iraq and Libyan wars.”

“Bashar al-Assad — how was I supposed to know he wasn’t a ‘reformer’?”

“I have no idea what in the world Susan Rice was doing vamping on five Sunday shows about an Internet video. I personally wouldn’t be caught dead doing even one.”

“What I lacked in policy accomplishments I made up in frequent-flyer miles.”
