Exactly what "threshold" did Hillary Clinton cross that prepared her to be commander in chief?

TalkingPointsMemo, quoting Hillary Clinton today, again suggesting that John McCain is more qualified to be president than Barack Obama (watch video of Hillary repeatedly praising McCain over Obama here):

“I think that since we now know Sen. (John) McCain will be the nominee for the Republican Party, national security will be front and center in this election. We all know that. And I think it’s imperative that each of us be able to demonstrate we can cross the commander-in-chief threshold,” the New York senator told reporters crowded into an infant’s bedroom-sized hotel conference room in Washington.

“I believe that I’ve done that. Certainly, Sen. McCain has done that and you’ll have to ask Sen. Obama with respect to his candidacy,” she said.

Calling McCain, the presumptive GOP nominee a good friend and a “distinguished man with a great history of service to our country,” Clinton said, “Both of us will be on that stage having crossed that threshold. That is a critical criterion for the next Democratic nominee to deal with.”

When exactly did Hillary Clinton demonstrate that she was able to "cross the commander-in-chief threshold"? When she supported Bush by voting for the Iraq War? When she supported Bush (and Lieberman) on the Iran resolution last September (basically a carbon copy of the Iraq war resolution)? When she went to Kosovo with Sinbad and Sheryl Crow? When she was First Lady of Arkansas? When she was planning the White House Christmas Party?

This is getting ridiculous. It's one thing for Clinton to build herself up. But constantly comparing herself to McCain, constantly praising McCain over the man who may be our candidate in the fall, is beyond annoying. Is that supposed to make her appear stronger? If she wants that comparison, we'll make it. On the most important foreign policy decision of this decade, on the biggest foreign policy disaster in recent American history, Hillary Clinton and John McCain made the wrong call - both sided with George Bush and voted for the Iraq war. If this is the judgment they would bring to the threshold of the Oval Office, if these are the decisions Hillary and McCain are going to be making when the phone rings at 3AM, who needs either one of them.
