As usual, it's election day, and you should go out and vote. I went this morning, and even with all of the problems with the board of elections this year, it was fairly quick and easy. I agree that the layout of the ballot is probably pretty difficult to read if you're elderly. I don't see why, for instance, they had to try and squeeze in party symbols (which nobody knows or cares about anyways -- who knew Democrats are represented by a star?) rather than making the party names large or legible.
Even if, like me, you feel like the decision was already made for you even before the primary season. Even if you're just a dispirited, or you live in a pretty uncompetitive district.
And if you don't know how to vote, or don't feel educated enough about the candidates/issues to vote, I highly recommend using the internet. Honestly, in this day and age you can actually find out an awful lot about candidates just by trolling the web.
Anyways, good luck with your democracy out there!
