Tuesday will be 21-days until the Presidential Election.  In NJ and many other states, tomorrow is the last day you can register to vote.  If you're waiting until the last minute, you can still get your registration in.  The easiest way is to go to NJ's Official Website
You can fill out and print the form in acrobat and print it with prepaid (free) postage.  Just don't forget to get it post-marked by tomorrow!!!
