Female votes....

It seems women have more voting power:

In recent elections, voter turnout rates for women have equaled or exceeded voter turnout rates for men. Women, who constitute more than half the population, have cast between four and seven million more votes than men in recent elections. In every presidential election since 1980, the proportion [of] female adults who voted has exceeded the proportion of made adults who voted. 

In 2004, 60.1% of women and 56.3% of men voted.
That's 67.3 million women and 58.5 million men - a difference of 8.8 million.

In 2000, 56.2% of women and 53.1% of men voted.
That's 59.3 million women and 51.5 million men - a difference of 7.8 million.

In 1996, 55.5% of women and 52.8% of men voted.
That's 56.1 million women amd 48.9 million men - a difference of 7.2 million.

In 1964, 67% of women and 71.9% of men voted.
That's 39.2 million women and 37.5 million men - a difference of 1.7 million.

In 2004
44.9% of women and 38.8% of men 18-24 years old voted
55% of women and 48.8% of men 25-44 years old voted
68.3% of women and 65.9% of men 45-64 years old voted
69.4% of women and 72.5% of men 65-74 years old voted
63.9% of women and 71% of men 75 years and up voted 

 Not bad for a "minority"...
