It's trite, but especially state/local elections have consequences. National stuff is big and sexy and well covered, but most of what affects our day to day lives is decided on the local and state levels.
I won't pretend I'm ultra informed on my neck of the woods. But everyone should be taking those elections seriously and at least doing a modicum of research on candidates before picking. There are a lot of good nonpartisan sources and organizations filling in for some of the local media gaps that make it pretty easy to get some general ideas at least.
