If you are a member of the female group your spokespersons are the likes of Hillary Clinton, Barbra Streisand, Nancy Pelosi or whatever shrew is the head of NOW or NARAL or Emily's List. All are loyal Democrats. Republicans need not apply for the job of shepherding the human ewes.
If you have Hispanic background, step in line and follow Gov. Bill Richardson into the Democratic sheep pen. And if you are a laborer or pipe fitter or an employee of federal, state or local government your shepherds are all loyal Democratic labor bosses.
This division of people into groups, and groups into political blocs, is necessary because the powers that be want to negotiate with groups rather than with individual Americans, and with group leaders they choose rather than with leaders chosen by the members of the groups. And when federal dollars are doled out, they pass through the sticky hands of the groups' leaders
And this is a party that allegedly celebrates diversity among individuals.
