You can't be afraid to put out a fire if you're a fireman. You can't be afraid to be a police officer and carry a gun if you're afraid to get up and go out there. So you've got to put that fear to the side and go out in faith to overcome that.
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.
