So, while I enjoy the posting of videos, it's hard to debate ... videos. Let's move to text.
As I understand it, this is what the argument is about.
https://www.commoncause.org/media/young ... on-common/Statement by Common Cause President Karen Hobert Flynn
The attack on Common Cause for our opposition to a constitutional convention by Cenk Uygur is both misguided and inaccurate. We agree with The Young Turks host and Wolf PAC founder on the need to overturn Citizens United, but we believe that we should use the path that has always been used in passing amendments to the U.S. Constitution: Congress passes the amendment and then sends it to states for ratification. Uygur’s call for an Article V convention is a very dangerous way to try to achieve that goal. The overwhelming majority of the democracy reform community is in agreement with Common Cause in opposing a constitutional convention, recognizing that even one convened for a single issue could very easily become a “runaway convention” capable of a massive overhaul of the Constitution and, worse still, one that would be driven by deep-pocketed special interests, like the Koch brothers. A constitutional convention is not the silver bullet Wolf PAC believes it to be, instead it is a potential Pandora’s box that poses a grave threat to our democracy.

BTW, I agree with KH Flynn here. This is absolutely a bad time for a Constitutional Convention. People paying attention have noticed it has been a Koch Brothers' agenda item for quite a while. They know with the current balance of power in state legislatures, a convention could lead to a bunch of amendments that basically do lots of things liberals would hate.
Common Cause is right.
We may not be able to get Congress to pass a Constitutional amendment overturning Citizens United right now, but I think it should remain a goal to get it done that way.
