From what I understand (coming from a medical family) is that the physician assistant program is a graduate program. Meaning it is a Masters. So you would need to get a bachelors in pre-med or another heavily science related degree first. Even if you go to school nonstop, get your bachelors then masters, it'll take the better part of 6 - 8 years. Granted physician assistants do not often have to do residencies, at least not for a great length of time like a doctor does. But if you are really going after politics, why not just do that in college for the next 4 - 8 years.
