Please remember, mamas, that voting for anyone other than Barack Obama or Mitt Romney is, in effect, the same as a choice not to vote - except that it is one that will also possibly give an advantage to one of those two candidates (which one is pretty hard to say right now). You may not like the real choices much, but they are far from the same guy and every responsible citizen must, at this point, choose to vote for one of them.
Personally, I would love to have a more parliamentary, coalition-y, less two-party system for certain, but we do not have one now and protesting that by wasting one's vote is childish. Working for that system is valid and admirable, but wasting a vote in the election we have is not. Also, even in our two-party system there is a pathway for working to choose a candidate who is to one's liking: the primary elections. A citizen who is not happy with the choices in November but who did not work hard to try to get a better choice in the primaries has little about which to justly complain.
Politics is real life. Every vote affects a real child. Being disgusted with the system is no excuse for not meeting your responsibility to those children by doing what you can do, even if it is not all that you wish you could do.
