It's more bizarre than anything else. Pelosi and the president are in separate spheres of government. Sure, they both have opinions on policy issues but so do the other actual presidential candidates.
And, of course, there's nothing at all in it for Pelosi. Who would consider it a coup to beat Perry in a debate these days? At worse, she "loses" and takes the hits, at best she "wins" and looks like she just took time out of her schedule to beat a Special Ed student.
Edit: lulz...
Ms. Pelosi wrote:
He did ask if I could debate here in Washington on Monday. It is my understanding that such a letter has come in. Monday I'm going to be in Portland in the morning, I'm going to be visiting some of our labs. I'm in California in the afternoon, that's two. I can't remember what the third is.
