Because we noticed that last week President Barack Obama's "approval" rating had for the first time slipped below his "disapproval" score in Gallup's daily tracking poll, it's only fair to report that he ends this very newsy work week with a six-percentage-point edge on the "plus" side:
-- The percentage who "approve" of the job he's doing: 50%.
-- The percentage who "disapprove": 44%.
Pollster.com has a chart that looks at a cross-section of polls. It's showing the president's approval and disapproval ratings basically tied 47%.
