Was using django-localflavor-us, but we needed an abbreviated list instead of the US_STATES that comes with it. So I yanked that, recorded a macro in vim and it did the work for me.

us_states_abbreviated.py

ABBR_US_STATES = (
    ('AL', 'AL'),
    ('AK', 'AK'),
    ('AZ', 'AZ'),
    ('AR', 'AR'),

    ('CO', 'CO'),
    ('CT', 'CT'),
    ('DE', 'DE'),
    ('DC', 'DC'),
    ('FL', 'FL'),
    ('GA', 'GA'),
    ('HI', 'HI'),
    ('ID', 'ID'),
