But try this (and actually, this might explain a little of why there was some cross-arguing last night). Go back to last night's thread Perry: Why I supported Al Gore.
Click on the article we were discussing. Look where you end up: Rick Perry backed an already-crusading Al Gore...
Recognize the article? It's the same article from this thread, just a different link to it.
Now, I don't really know when Ben updated his article and changed the name and republished it. And in retrospect, you might not have noticed this.
I noticed it right away because I went to the article to read it, thinking it had more information that might change my opinion from last night (yes, despite the opinions of some around here, I actually read most of what people link me to, as a speed reader it's not hard).
I immediately recognized the picture, and the first few paragraphs were exactly as I remembered them (I pretty much memorized the article from last night, I read through it so many times trying to see what my opposition was seeing).
So anyway, to answer your questions, it is not a different article, and it does not appear to have different content. It is possible that the content of the article changed during last night's discussion, but it hasn't changed since I joined the conversation, so far as I can tell.
Another reason why Politico isn't the best place to get news, their penchant for changing articles out from under you and changing the titles to deceive their readers that it's different.
