Will George Bush speak at the DNC?

This market will resolve to "Yes" if former US President George W. Bush is a speaker at the Democratic National Convention. Otherwise, this market will resolve to "No". This person will be considered a "speaker" if they publicly speak in-person at the convention to an audience. The primary resolution source for this market will be official information from the Democratic party, including footage from the convention, however a consensus of credible reporting will also be used.
