Hmm.. Isn't that a rather minimalist practice of good Citizenship? I am pretty sure most people won't benefit significantly differently, individually, based on who becomes the next President. But the overall direction of our Civilization can change dramatically – as the last 8 years have demonstrated forcefully. I think being a little more concerned about the future of Community/State/Nation is not entirely useless.
Yes, this would be minimalist..But for some, motivating to be a "minimist" to effect change is better than being do-nothing-and-play-victim-ist. And yes, i feel sometimes you need to think about yourself first before you can take care of others.
For example: tax issues: If I give 30-40% of my income to say the under a robin-hood bailout plan, for example, I jeopardize my own family and self livelihood, not to mention, no one learns from this who gets bailed out. If I can decide keep and decide to down with the 30-40%, I could use it to start a company (for example), which if successful, would create jobs. Perhaps this is a very narrowminded and naive-thinking.
