Barack Obama's campaign is set to open its -- get this -- 37th office in Missouri this evening in, of all places, Lee's Summit.

"Of all places" because Lee's Summit is like Olathe -- a haven for Republicans, and organizers say that Democrats can't recall a time when a Demo presidential campaign opened an office there.

But open it will at 6 p.m. tonight at 234 NE Chipman Road. The Girardeau Family, who hosted Obama in its home Monday night, will be there. So will Lee's Summit Mayor Karen Messerli.
