Sen. Obama can do what he wants

Seriously, I don't know what Michael Crowley at TNR is thinking saying:

More handwringing about Obama's optics: I see that tickets for his acceptance speech at Denver's Invesco Field stadium sold out instantly. In light of the apparent traction Republicans got with their 'Celebrity' meme you have to wonder if the Obama team is reconsidering the wisdom of this move. I would recommend any possible stagecraft to minimize the event's scale.

What traction? With political pundits? I don't see any polls that support this "traction" idea. Why minimize it? Why think small? When was the last time anyone generated this much excitement? The Republicans are just jealous, small, and petty. You are going to have 75,000 people excited about politics. It's not like Sen. Obama is going to get on the stage and sing "I Kissed A Girl" to them - no, he's going to have a serious discussion about the future of our country.
