The problem with the back and forth here is all of you are thinking in the same paradigm as you did 4 years ago. And that's the problem. Same old paradigm.
There isn't one single solution to what ails the US political system, but there is widespread agreement across the political spectrum as to what ails it: corporate ideological control of the two party system.
The reason your boy's (and your) plan won't work Don, is because the corporatocracy (or the corporate wing of the Democratic party, if you prefer) won't allow progressives to take control of the party.
I can't believe that isn't bloody obvious to everyone by now.
Both Obama and Clinton are corporate wing Dems. Both McCain and Romney are corporate wing Repubs.
Your choice is the flavor. Some folks shop at Wal Mart, some at Target, some at Amazon.com.
Doesn't matter. The US political system has been bought and paid for, and no one, unless they are willing to make drastic changes with the stroke of their pen the way the Bush administration has (ie, through the use of executive orders), can change much of anything.
You have to give Bush/Cheney this much--they went petal to the metal from day one, overturning nearly 50 years of Democratic rule.
You think Clinton or Obama will do the same? No, they won't because they are both corporate controlled chicken shits.
