You realize that Gallup is also a 7 day poll ( Not sure about Marist ), unlike Rasmussen and I believe the Florida one so it will take a few days for them to catch up.
Also I would suggest you check the internals of the Marist poll, the only way for it to come out to even being close to being true is if Democratic Voting levels are close to 2008, and we both know that is not going to happen.
