I have also reserved domain www.votecpr.com

Would you prefer a design just on the front of the shirt, or a design that incorporates both the front and back?

I would not be against front and back. Perhaps a tickler logo or something alluding to the CPR small on front with the major design on the back? You seem to get the idea. I just want it to be very clear of the tie between CPR and "Comprehensive Politician Reform".
Thanks
