In keeping with the March Madness national college basketball tournaments, The Daily Show developed its own tournament:  Third Month Mania.

Beginning with 64 issues that make Americans mad, the issues were divided into four categories (see below–People, Issues, etc.) and the winners of the four categories faced each other in the playoffs.  Viewers voted online six times, just like the six rounds of basketball competition, and results were reported each night on the show.

Of all 64 issues, what makes Americans the maddest?  Trump supporters!

Note:  To see all 64 entries, go to thirdmonthmania.com.  Winners are in white.

Most maddening: Trump supporters!
