I tried to argue in this thread:
http://www.democraticunderground.com/discuss/duboard.php?az=show_topic&forum=104&topic_id=1176043that perhaps the number one on my list there(reform of voting methods, proportional representation, pairwise counting methods etc) is something that a broad base of support could be built around (from all sides of the political spectrum).
I thuink this is so because.
#1 It crosses party boundaries and would be more likely to produce "spin offs" that also cross such boundaries. It reaffirms something we all trust and want more of. Democracy.
#2 It is a super easy sell. We aren't talking about wild theories but solid mathematical studies of voting done long after 1789 when the constitution was created. Most modern democracies have adopted some of these measures.
#3 The only real reason to oppose it is raw, naked party interest so it will tough for politicians to say no.
#4 With a better system for representing the populace and more voices , we will get more and better solutions to problems. This is the lynchpin I think. Once we fix the institutions and practices that are hampering true Democracy (gerry-mandering etc) where we all want to head will much more easily fall in place.
