I say you vote - and take a stand. There are far more things out there in the world that can affect you both on local and federal levels and one should pay attention.
For instance it caught my attention in the Congress soapbox:

I really began to think - WTF? When did this one happen and how'd it slide under the attention of others.
Its things like that where one should pay attention because that COULD defenitely affect you.
Yes you might protest the candidates or policies, but at least go with a penciled in guy or show you don't like how things are going by voting in or out the people that you consider the lesser evil so you can remove them later.
