From the Arlington County Democratic Committee:

Arlington will be represented at the 8th  Congressional District and State Democratic Conventions by elected delegates and  alternates. There are four categories of positions: Clinton delegate, Clinton  alternate, Obama delegate, and Obama alternate. These delegates and  alternates will be expected to attend (at their own expense) the 8th District  Convention on May 17 in Alexandria and the State Convention on June 14 in  Hampton.

There is an excellent description of the  delegate selection process for these positions on page 4 of the April issue of  the Voice—the Arlington Democratic Newsletter. If you want to learn more, or  think you might be interested in becoming a delegate or alternate, log on to our  website [and]  click on the link on the left side of the homepage that says “Read the  Voice”.
