Recently, AIGA had a contest called "Get Out the Vote 2008" where designers submitted designs for posters encouraging Americans to vote. Above are some of my favorite winning posters.

Visually, the Obama/Biden posters are more visually appealing to me, but I also think the Optima typeface is strong and works to convey McCain's reputation as sturdy, patriotic and dependable. Regardless, both campaigns have fully embraced the importance of strong branding.
What do you think?
