People often say that if you don't vote, you don't have a right to complain. It isn't that simple, though. In my own state, we are about to elect a new senator. The incumbent is a spineless wonder who masquerades as a Democrat. There is another Democrat running whom no one's ever heard of, and there are three Republicans: a far right-wing religious nut, a moderate Republican who had made some terrible racist comments, and a W-worshiper. I will vote for the incumbent--the least of the evils--but not with any enthusiasm.
One need only to look at the recent Congressional proceedings regarding Iraq to realize how little true debate and dialogue there is on a national level. And who in Congress is doing anything real about issues that affect people's health and welfare? Anyone remember Dioxin toxicity? Or women's rights? Or how about the fact that if your insurance won't pay for the only medicine that works for your condition, then you're stuck with paying for it yourself? And what about the totally impossible Social Security disability system? Or child abuse?
Many of us vote, but I don't think many of us expect much to change.
