Horsey has been recognized for his work with numerous awards over the years, the most notable of which is the Pulitzer Prize for Editorial Cartooning. He received this award first in 1999, when many of his cartoons focused on the Monica Lewinsky scandal, and again in 2003, when he often lampooned the Bush administration. His editorial position is anchored firmly on the left, and he eschews any criticism of the Obama administration. He is highly critical of Christians, Republicans, and the Tea Party. He is strongly supportive of the LGBTQ community.
