Democrats are offering an online primary for those living abroad. Sign up-- especially if you're like me and have been putting off trying to figure out the whole absentee ballot thing.
Speaking of which: http://www.votefromabroad.org/ has an easy fill out the form, print it, sign it, fax or mail it absentee ballot sign up thingy. It will also take you through signing up for DA.
Just an FYI =)
