The Democratic National Convention is in full swing. The speeches have begun and so have the parties. The Sunlight Foundation is keeping track of them, not for the celebrities, but to monitor the influence of corporations, special interest groups, and unions on lawmakers. The group was on the ground in Tampa and is now in Charlotte for the DNC. Keenan Stiener with the Sunlight Foundation joins WFAE's Duncan McFadyen to talk about the mix of politics and parties this week.
