While that is true. That would never work. There is a movement we are dealing with called reset america.
www.resetamerica.com that wants to pretty much do that. I can only speak for the green party when I say that the differences are very large.
Case and point...the first second a Green candidate mentions universal health care the libertarians would drop him like a rock or visa versa.
The Greens are trying to build a party to compete with the 2 big boys. We don't want to become a marginalized 3rd party conglomerate.
I am at the Green Party national convention right now and this stuff is being discussed non stop.
