Attention US citizens: vote.
Need another reason, one you may not have thought of or heard? Here it is:
How public largess, a.k.a. tax money, is distributed is most definitely connected to the proportion of citizens voting in an area. You know what they say about squeaky wheels and grease? And that nothing talks louder than money?
Well, for a limited time only -- today -- votes talk louder than money.
Make sure you get yours.
(Why, no. As a matter of fact, I am not above bribery on important things like voting. Enlightened self-interest can be a Beautiful Thing.)
