From the "American Prospect" by Ben Adler.

With an estimated 37.5 million eligible voters with a disability -- and the aging baby boom generation means the ranks of the disabled will grow -- disability rights is an emerging brand of identity politics. The Democratic Party has been attuned to the change. The Democratic National Committee disability caucus is growing in size and prominence. The Obama campaign had a comprehensive disability-issues platform, and President Obama hired Kareem Dale to be the first White House special assistant for disability policy. On July 21 the president also announced the U.S. will sign on to the United Nations Convention on the Rights of Persons with Disabilities.
