What started as a Facebook event a few weeks ago has turned into a serious event worth considering, with more than 100,000 pledging to attend.
The Facebook event, currently being administered to by four grassroots supporters, has received over 109,000 RSVPs. It proposes to gather 100,000 Sanders supporters for a rally in Washington, DC.
The grassroots organizers of the rally pitched the idea to staff from the Sanders campaign in a conference call on Wednesday. The official campaign has not yet made any commitments to get behind the proposed event.
If this planned event did go ahead, and attracted attendance in the hundreds of thousands, it would be a serious historical milestone in American politics.
