When Runyon and his cronies are plotting on how to reject Senator Hanson's nomination, Runyon's cigar goes from smaller to larger as the scene progresses.
In the yacht scene, a close-up of the President's West Point Ring can be seen. This reveals the Academy Crest facing away from the heart (as if saluting). Upon Graduation from West Point, graduates face the Class Crest away from the heart and the Academy Crest towards the heart.
Senator Hanson is seen jogging in what is undoubtedly meant to be Arlington National Cemetery. Jogging is not permitted in Arlington National Cemetery, and presumably a U.S. Senator would know better than to be seen disrespecting American veterans in such a way.
Someone nominated to be Vice President would not be allowed to jog alone in a cemetery. They would have Secret Service protection.
Towards the end of the movie when the President is addressing Congress, Joan Allen is seen outside of the building jogging. Joan Allen, being a senator and therefore a part of Congress, should have been inside the building.
At one point Runyon says that an article will appear in the next day's "afternoon edition" of the Washington Post. The Post is a morning newspaper.
Within seconds after the car, which had closed doors and windows, hits the water it permanently sinks below the surface.
Trapped air causes cars with closed windows and doors to initially resurface due to the air trapped inside, which escapes slowly as water gradually seeps into the cab through small openings to the outside.
As soon as the Senator swims to the car it is completely filled with water, but all doors are closed and all windows are all the way up.
The only way a car could have immediately filled with water is if there were a massive opening, such as all windows being down or a door or two being open, as it plunged under the surface front first.
Also, if the car were completely filled with water with all doors and windows closed as it was shown to be, the occupant could have easily opened the door by herself because the pressure on both sides of the door would have been equal.

When Senator Hanson is jogging in the cemetery, several of the tombstones bear the name "Col. Stone T. Berg".
Near the end of the movie when the President is walking onto the podium to give his speech to Congress, the camera pans across the back of the Assistant Cameraman wearing a gray ball cap and holding the remote focus device for the camera.
When Runyon and Webster are speaking for the first time, they pass a room in which a chandelier that appears to have a black flag (a piece of grip equipment used to block glare from lights) attached to it.
When Hathaway walks out the doorway of the Oval Office to meet his wife in the hall, in the edge of the doorway can be seen a reflective card presumably set up for lighting purposes.
In the final speech that President Evans gives, you can clearly see a mic boom operator and his boom as the camera pans to the left to view the audience.
When the Senator is going with her husband to meet the President for the first time, the Lincoln Memorial is clearly seen is the back window of the limo, indicating that they are leaving DC on the Memorial bridge, heading in the wrong direction.
Timmy Hanson says "being the vice president is better than being the president...'cause nobody wants to shoot the vice president." That isn't quite true. In 1804 sitting vice president Aaron Burr infamously dueled against former secretary of the treasury, Alexander Hamilton. Hamilton's shot missed Burr while Burr's shot mortally wounded Hamilton, who died the next day. Burr was later tried for murder but acquitted. However, the character who says this is six years old, and probably does not have such an extensive history knowledge.
