Best known for the being the Republican that whooped Sam's pretty little ass on Capital Beat, Ainsley joined the Bartlet administration as an Associate White House Counsel after Bartlet was impressed that she was quick enough to nail Sam. CJ thinks she murders and mutilates her pets, though Ainsley claims to not have any.
A native of North Carolina, she is daddy's little Republican sweetheart, and calls to tell him when Sam asks her for help. She was a Young Republican, and stayed true to this despite having gone to Smith for college. She is against the ERA, is afraid of peeing on carpets, doesn't think she looks like Donna, and played the trombone which caused her to meet interesting men. Sam called her a blond Republican sex-kitten. Hee.
Her office is the Steam Pipe Distribution Room, which gets rather steamy when the heat in the building goes on. She's quite fond of Gilbert and Sullivan, gets sick when she drinks too much (which must be like, what, two drinks?), has a HUGE sense of duty that is rather easily appealed to, and has this strange habit of forming incredibly odd speech patterns when she is nervous.
In conclusion, she drinks pink squirrels, gets drunk easily, dances to old 50's tunes in bathrobes, and eats muffins like a demon. Oh, and gosh darn it, the White House should carry Fresca.
