With a nod to Irwin, for posting this info in an early entry - I think this deserves a post all its own.
Early voting is an option in Idaho and here is a link for the different counties in the state. Scroll to the bottom and click on the County name to see specific voting instructions for each voting system.
If you are in Ada County here is the link. Early voting started today and closes Monday, November 3, 2008. Polls remain open from 8:00 am to 5:00 pm Monday through Friday at the following location:
Ada County Public Safety Building
And in Canyon county at the County Elections Office, 1102 E. Chicago, Caldwell
Also I thought the Statesman did a nice Voting 101 article. It will help you make sure you have the proper identification with you and such.
I would suggest that these are some nice links for each of us to keep handy; so that we can be a resource to others in our circle of influence - and to help Get Out The Vote!
