Today's Gallup tracking numbers give Barack Obama a five-point national lead over Hillary Clinton, up from the virtual tie in yesterday's results:

Obama 47% (+1)
Clinton 42% (-3)

There was some question as to whether Obama's numbers yesterday were being dragged down by the Hillary camp's plagiarism accusations. But with this strong recovery, it looks like it might have just been a statistical blip — and even if it wasn't, the publicity from his big Wisconsin win should make it a moot point.
