The United States has never had a female president. To what do you attribute this

There has never been a female president because a majority of Americans are afraid of change. Many people are afraid of change and don't want to find out what it would be like to have a woman president. Men have been running our country for decades and so by now, we have grown accustom to that, so to go and change what we are comfortable with would create a lot of fuss. When we have our comfort zone, we don't want to let anything new in or change anything. By not allowing anything new into our comfort zone, we are never able to experience something new and exciting or something new that could be for the better, but we would never know.
