I do not feel it is appropriate for some construction worker with a GED education that spends his leisure watching baseball to have power to cast a vote for a President of the United States and for a Congressman based to a great extent on what he overheard his pastor saying on Sundays in Church. The majority of American voters are not far from this example.
Lets face it, most people either do not vote in the elections or don't have a clue beyond TV ads what any of the candidates is looking to do and what exactly is going on in the World.
More than that, mindless discussions about abortions, gays, and elusive universal health care take a big chunk of political debates election in and election out.
See, I would be in favor of Democracy if there were education and/or test requirements to vote in elections and the candidate manner and substance of discussion were more in tune with real life events.
