Hi Jessica,
My first impression of your personal statement is that it focuses too much on the negatives. Essentially, your story boils down to this: you worked as a staffer on the Hill, became disillusioned with the legislative process (you and everyone else
, and so you've decided that a career in law will be more suitable given your career aspirations. Unfortunately, law school sounds like a Plan B. It shouldn't. I'd be interested in knowing how your work in the US senate informed your decision to go to law school in a positive way: did you become particularly interested in certain policy issues? Would you like to go into politics after law school? What about public interest/advocacy?
Also, I'm afraid your career plan (as you described it from the perspective of a college freshman) sounds both overly ambitious and slightly misguided: few college students move to the Hill and immediately start shaping public policy. (Most have graduate or law degrees, so your decision to go to law school is essentially correct. You do, however, need to work on how you present it.) It is overly premature to declare your "career in politics" over, especially since you only worked for the US Senate for two years after college. It gives the impression that you give up too easily, which not only plays into the stereotype of the fickle Millennial, but it also raises a red flag about whether you'll be happy as an attorney.
Keep in mind this is all purely subjective, and others might have a different view on this issue
Good luck!
