What's a "woman's issue"?

"Every issue today is a woman's issue -- the defense of our country, our economy, education, healthcare, and protecting the environment. To get more women into public office, we must get more women involved in politics. What people don't realize is that even a small amount of time volunteering can make a difference. Can you make a few phone calls? Can you lend your home? Help write press releases? Work for what you believe in, whether it’s on a local, state, or national level."
