In March 1913, less than two months after the sorority's founding, Deltas marched down Pennsylvania Avenue in Washington D.C. for women's suffrage. Delta's political activism is alive and well in the Bloomington-Normal Alumnae Chapter (BNAC).

Voter Registration - BNAC conducts voter registration drives at the Cultural Fest and Juneteenth, in addition to drives at local businesses and churches.

Delta Days in Bloomington-Normal-- On the second Monday in May in Bloomington, and the first Monday in June in Normal, BNAC celebrates Delta Days at the City Council.
