A Congressional Conversation Index says that members of the House of Representatives received the most communications from constituents about defense and immigration in May, while in January the leading issues were health and women's issues.
The index, launched by Adfero Group and Fireside21, measures communications received by participating House members. Communications vary from letters and e-mails to phone calls and in-person visits to a House member.
Constituent communications on health issues hit 2,540 in March, compared to 334 in February and 135 in April. The House passed the landmark healthcare bill in mid-March.
