grampster, thanks for flushing that out for me. I see where you're coming from. Ultimately these huge voting blocks are composed of individuals. As one of these said individuals, it's up to me make my one vote. The other 300 million odd persons in the USA get to do the same.
Let me try to explain my perspective on this:
It's frustrating, as an individual - I spent some time reading about various state and national politics. I feel like I had a pretty good idea on what the platforms had and stood for, and voted accordingly. But, my wife's ditzy friend, who doesn't know or even care about any of that voted for Obama because, "OMG, I can say I voted for the first black president, what a historic moment!"
And, our votes effectively canceled out. It doesn't matter if I spend every waking hour studying politics or not - it's not going to make my vote somehow worth more. My precinct voted for Obama by about 5300 votes, which isn't a lot, really. But, as an individual, with my vote, what would have changed if I voted for Obama? The count would be 5301. Thats about it. What if I hadn't voted at all? Nothing would have changed.
But, I vote for who I think will be the most effective leader. But that's not enough.
Sure, I could spend every waking hour trying to educate the people who live in this city, and try to sway them towards my viewpoint. But, any difference I could make would still be just noise compared to the shifts in opinion generated by the mass media. What's the point?
