Josiah Bartlet
Josiah Edward "Jed" Bartlet is a fictional character from the television serial drama The West Wing, portrayed by Martin Sheen. He is President of the United States for the entire series until the last episode, when his successor is inaugurated. Bartlet is one of the main characters of The West Wing, and he appears in all but thirteen episodes (142 of the show's 155 total episodes).
In many ways, Bartlet is an "ideal" president. He is handsome and endowed with great personal integrity, a sense of humor, a fierce intellect, and a toughness tempered by compassion. These traits helped boost his popularity in the show to a point where he has been referred to as the "most popular Democratic president in recent memory."
