I want to get mail or email address for Geraldine Ferraro, former
Congresswoman and vice-presidential candidate.

Dear Gabe, 

According to an autograph collector's site, the address is: 
22 Deepdene Rd  Forest Hills, NY 11375
(SOURCE: Steve's Sigs Addresses
<http://members.tripod.com/~stevesigs/addresses.html>).

This is also the address mentioned in other celebrity sites: 
Celeb Central
<http://www.celebscentral.net/address/3401/> 

Ferraro is a member of the Board of Directors of the National
Democratic Institute. You may want to try their address (with c/o
Geraldine Ferraro) alternatively, or if the first one wouldn't work:

National Democratic Institute
2030 M Street, NW, Fifth Floor
Washington, DC 20036-3306
tel: (202) 728-5500
fax: (202) 728-5520
contact@ndi.org

I hope this answers your question. Please contact me if you need any
clarification on this answer before you rate it.
