This is pure speculation, but for a period of time, a lot of getting into a party was through fundraising and volunteer work, and Republican women had more time to do that than democratic women, who were out there getting jobs.
I started working at a soup kitchen in skid row of Los Angeles when I was 13 years old, and the first day, I felt really scared. I was young, and it was rough and raw down there, and though I was with a great volunteer group, I just felt overwhelmed.
Be of service. Whether you make yourself available to a friend or co-worker, or you make time every month to do volunteer work, there is nothing that harvests more of a feeling of empowerment than being of service to someone in need.
