Yesterday Microsoft became the "official software and HD web content provider" for the 2008 Democratic National Convention. I'm not entirely sure what the software part entails, but the HD web content provider means that we'll be seeing a lot of Silverlight content coming out of the DNC. In fact, Silverlight will help provide live coverage of the event, one which I think should be well viewed considering the state of the Democratic race. As Larry notes, Google is the official "innovation provider" for the Republican National Convention in February.
One cool bit which I haven't been able to get a lot of extra information on is the fact that Microsoft is providing the technology behind real-time online voting systems. Is that going to be a WPF application? Will it be using Windows Communication Foundation?
One thing Microsoft does a pretty good job of is showing off good looking rich media demos. The DNC will be a good place to do that. I'll update the post but I'm really curious which agency will be working on the end user application. As an RIA fan, I think this could be a good way to show of a high quality RIA experience to mainstream users. Maybe even more so than the Olympics because of the data involved in a political convention.
