Grasping that Americans respond well to sweets, particularly free ones, the following places are giving free stuff to people who vote:
Starbucks (free tall cup of coffee)
Ben and Jerry's
I'd like to avail myself of all of them to show my support for their, well, support. But that being vastly more sweets than I consume in a week much less a day, I think I will content myself with just hitting up one of the ice cream places and calling it a day.
