This is purely conjecture on my part.
But I noticed that Obama has NOTHING on his schedule after the Rhode Island appearance at 12pm eastern. Maybe it's simply left out, and of course he needs time to fly back to where ever.
But maybe, just maybe, he has a surprise in store. Shall we say, endorsement by, oh Richardson or Edwards, or both?
Or am I simply reading way too much into this.
Thoughts/comments?
