These are examples of print ads from Snickers' "Don't Vote Hungry" campaign developed by BBDO New York. as part of the ongoing "You're Not You When You're Hungry®" campaign.  "Don't Vote Hungry" also included distribution of Snickers candy in Iowa on Election Day (Iowa City Precinct 5).  Later a video was produced documenting the campaign. 

from Little Black Book:

SNICKERS and BBDO New York have launched an election-season adaptation of the brand’s ‘You're Not You When You're Hungry’ campaign. The idea, ‘Don't Vote Hungry’, urges consumers to eat a SNICKERS before voting to avoid confusion come election day. 
The work will appear in print, outdoor media, social media and on bumper stickers. SNICKERS samples will be distributed in Iowa, a key swing state in this year’s election, to help voters not vote hungry.
