When someone holds a party in your honor, you generally want to thank them by name. When someone throws a party in your honor and charges each guest $35,800 to attend in order to put the money in your campaign chest, you want to thank them by name — and you probably want to make sure you get the name right first:

The president told a $35,800-a-couple Medina fundraiser that the 2012 election will be “especially hard because a lot of people are discouraged” but vowed he will “keep drawing a clear contrast” between his vision of America and that of the Republicans.

The fundraiser was held in the 27,000-square toot, art-draped home of former Microsoft chief operating officer Jon Shirley. Obama deemed the art collection unforgettable. But he could not remember the name of his host.

“I was saying to Mark that I wish I had time to just roam around because this is as beautiful a collection as I’ve ever seen. I want to thank Mark . . .” Obama said. A couple of guests said “Jon,” and the president quickly corrected himself.

The Boss Emeritus refers to a pertinent quote from the First Lady in June:

“See, what you all need to know about the President you helped to elect is that when it comes to the people he meets, Barack has a memory like a steel trap[.]”

Well, if he can’t even remember the people who raise millions of dollars for him, something tells me he’s not going to do much better with people who aren’t putting cash in his coffers.

Got an Obamateurism of the Day? If you see a foul-up by Barack Obama, e-mail it to me at [email protected] with the quote and the link to the Obamateurism. I’ll post the best Obamateurisms on a daily basis, depending on how many I receive. Include a link to your blog, and I’ll give some link love as well. And unlike Slate, I promise to end the feature when Barack Obama leaves office.
