The Daily Show with Jon Stewart recently targeted the sudden evolution of marriage equality supporters in Congress, including Democratic senators Bill Nelson, Kay Hagan, and Claire McCaskill, plus Republicans Rob Portman and Mark Kirk, whose recent stroke led to his change of heart.

Stewart joked that this all this talk of evolution refers to Charles Darwin's Theory of Gay Evolution, which led to Darwin’s Evolution of Gay Marriage Acceptance Chart, a classic sight gag.
