For anyone who would vote except for the feeling that neither major party represents your point of view, there are almost always "3rd party" candidates on the ballot. Consider whether one of them might be more in line with your philosophy. Generally they are not invited to debates, etc, because they draw so little of the vote... and truthfully, most of them are not very 'serious' candidates. But, if your general philosophy is Libertarian, say, just giving them a larger percentage of the vote gives them more access to the ballot and the like.
I don't make my decisions based on advertisements. The nice thing about elections today is that nearly every candidate or ballot issue will have a website, where you can find information, and you can easily access newspaper editorials, etc. One of the most wonderful resources is http://www.ballotpedia.org, which has neutral summaries and links to pros and cons for various races.
Voted for the next group who regardless of party will probably screw us over! Yes, I am jaded and distrustful, but I did my civic duty so that I can complain in the future.
