Bruno says he's going home to Essex County, New York, where he has a big house on the Hudson River. That likely puts him in Newcomb, New York, where the Hudson River resembles more a brook than a river.
The Santos house features three different staircases in three different episodes.
In Impact Winter (2004), the staircase inside the front door to the house can be seen leading away from the door to the left of the hall.
In Running Mates (2006), the staircase can be seen coming down from left to right behind the door in a number of scenes,
In Election Day: Part 1 (2006) and Election Day: Part 2 (2006), the staircase has changed yet again, now curving upwards from the right of the door. Either Helen Santos has been doing some extensive remodeling, or different sets were used in each episode.
Louise Thornton (Janeane Garofalo) mispronounces "Oregon" several times. This is consistent with the character having spent her childhood, education and career in the Northeast, and thus being unfamiliar with Western place names.
