The stumbling you jumped on sounded like exhaustion  to me, or a sound system distraction, or both combined. Who knows? Seek not so much to be understood as to understand, to give compassion, or how about just give a guy a break.

Hmmm...one must wonder if there would have been as much "understanding" and "compassion" or willingness to "just give the guy a break" if "the guy" had been President Bush, "exhausted" or "distracted" and delivering one or more of these gems as reported by Michelle Malkin (yeah, yeah, I know, another "ring-wing shill", blah-blah-blah):

In May 2007, [Senator Obama] claimed that tornadoes in Kansas killed a whopping 10,000 people: “In case you missed it, this week, there was a tragedy in Kansas. Ten thousand people died — an entire town destroyed.” The actual death toll: 12.

Last month, in front of a roaring Sioux Falls, S.D., audience, Obama exulted: “Thank you, Sioux City. ... I said it wrong. I’ve been in Iowa for too long. I’m sorry.”

Explaining last month why he was trailing Hillary Clinton in Kentucky, Obama again botched basic geography: “Sen. Clinton, I think, is much better known, coming from a nearby state of Arkansas. So it’s not surprising that she would have an advantage in some of those states in the middle.” On what map is Arkansas closer to Kentucky than Illinois?

Obama has as much trouble with numbers as he has with maps. Last March, on the anniversary of the Bloody Sunday march in Selma, Ala., he claimed his parents united as a direct result of the civil rights movement: “There was something stirring across the country because of what happened in Selma, Ala., because some folks are willing to march across a bridge. So they got together and Barack Obama Jr. was born.”

Obama was born in 1961. The Selma march took place in 1965. His spokesman, Bill Burton, later explained that Obama was “speaking metaphorically about the civil-rights movement as a whole.”

In Cape Girardeau, Mo., Obama showed off his knowledge of the war in Afghanistan by homing in on a lack of translators: “We only have a certain number of them, and if they are all in Iraq, then it’s harder for us to use them in Afghanistan.” The real reason it’s “harder for us to use them” in Afghanistan: Iraqis speak Arabic or Kurdish. The Afghanis speak Pashto, Farsi, or other non-Arabic languages.

Over the weekend in Oregon, Obama pleaded ignorance of the decades-old, multibillion-dollar massive Hanford nuclear-waste cleanup: “Here’s something that you will rarely hear from a politician, and that is that I’m not familiar with the Hanford, uuuuhh, site, so I don’t know exactly what’s going on there. (Applause.) Now, having said that, I promise you I’ll learn about it by the time I leave here on the ride back to the airport.”

I assume on that ride, a staffer reminded him that he’s voted on at least one defense-authorization bill that addressed the “costs, schedules, and technical issues” dealing with the nation’s most contaminated nuclear-waste site.

And in perhaps the most seriously troubling set of gaffes of them all, Obama told a Portland crowd last month that Iran doesn’t “pose a serious threat to us” — cluelessly arguing that “tiny countries” with small defense budgets can’t do us harm — and then promptly flip-flopped the next day, claiming, “I’ve made it clear for years that the threat from Iran is grave.”
