This is a point I made in the last post as well, but voting does matter. It may not matter a lot, but aggregate vote totals affect ongoing political strategy (i.e. selection of battleground states; willingness of national parties and PACs to invest in local candidates) and may play a role in setting national policy (i.e. the current majority vote electoral college reform effort). It is an historic record of an opinion, and affects the way in which we understand ourselves as a society. I don't think these are merely 'psychic' benefits, but we seem to have otherwise divorced the concept of citizenship from any sense of obligation. I think we need to bring it back: membership has its privileges, and it should also have responsibilities beyond merely obeying the law.
There is no such thing as a non-battleground state. Not voting for Obama in Oklahoma, Kansas, Alabama, etc., means that these areas will continue to be viewed as non-battleground states where the minority of voters can be safely ignored, where the Democratic party will not “waste” money or other resources to aid local candidates or shift discussions, where Republicans will feel empowered to continue building their New Confederacy. There is a political battle going on EVERYWHERE, and while voting in the minority isn’t necessarily fun, it still should count for something. And people in “safe” states who would throw away votes need to remember that polling is a social science.
Arguments against voting make me very cranky. Though there are really interesting moral issues at work here. Also here:
my vote is an endorsement of the policies of the person who gets my vote ...as better than the alternatives overall. I reserve the right to disagree with candidates I vote for, and to criticize their policies after they win. And while I may bear some responsibility for policies that were discussed in the campaign, policies which were not significantly in play — or easily foreseeable — during the election are not my responsibility. How, in a two-party system — or even in a 10-party system — can anything else be true?
