This is REALLY a no-brainer...
AL- JEEETUH! He's batting .343, OBP is .417. Pretty big numbers for a shortstop. Add to that the fact that he's the unquestioned leader of the GREATEST team in baseball and his "D" and you've go yourself an MVP.
NL - Pujols. Do I even NEED to put up stats here? OK, fine. Some people are on Howard's nuts (58 HR) but look at the rest. Pujols: Avg. .331, Slg, .671, HR 49 and 137 RBI's. Plus, he's BEEN doing that. Not tosay that Howard won't, he's just not as good or as complete as Pujols is yet. Also, Pujols is a leader.
