This was one of those times when Mika did her job. (So did Steve Rattner.) And the deer-in-the-headlights look on Carly Fiorina's face is a joy to behold:

MIKA BRZEZINSKI:, MSNBC: You said [Hillary Clinton] does not have a track record of accomplishments, why do you say that?

CARLY FIORINA: She really doesn't. Yes, she’s had a lot of very impressive titles, but a position is just a position — it’s all about what you do in it, and I think her time in the position of secretary of state is demonstrably one that lacks accomplishment but that also has some real blemishes on it.

It’s a problem when you mislead the American people for a month about what really happened in Benghazi. It’s a problem when you believe that Vladimir Putin can be thwarted by a red reset button. I’ve met Vladimir Putin. I sat across the table from him; there’s no way a red reset button is going to work. It’s a problem when our relationship with Israel has deteriorated so dramatically, and it’s a problem when terrorism is on the rise, not on the wane as she and the president continue to try to convince the American people...

And just the fact that she’s running for president is inspiring to many women — I take none of that away from her.

MIKA BRZEZINSKI: So I’ve been reading and listening to your criticism of her that really are quite searing, again, focusing on her track record of accomplishment. And I’m just wondering, when you talk about blemishes, you have an amazing round of accomplishments in your life, but someone could say it like this:

You ran for Senate and lost. You worked for John McCain and you were moved off that campaign and he lost. You had a tenure at Hewlett Packard that a lot of people describe as extremely rocky; destroying jobs, and destroying the company’s reputation. Are you really the right person to be criticizing Hillary Clinton’s accomplishments or lack thereof?

CARLY FIORINA: Well you clearly have been reading the Democratic talking points. Let’s just start with Hewlett Packard. We accomplished a lot at Hewlett Packard; we doubled the size of the company.

Watch the whole thing, you'll enjoy it!
