**FILE PHOTO (NYT34) NEW YORK -- May 30, 2005 -- CHENEY-SISTERS -- Elizabeth Cheney, left, took the stage at the Republican National Convention in New York on September 1, 2004 with her parents, Vice President Dick Cheney and Lynne Cheney; her husband, Philip J. Perry; and her children. Like the Adamses, Roosevelts, Tafts, Kennedys, Gores and Bushes before them, the Cheneys are a family act, a foursome fully immersed in conservative politics and public policy.
