"You take the blue pill (Obama), the story ends, you wake up in your bed and believe whatever you want to believe. You take the red pill (Romney), you stay in Wonderland, and I show you how deep the rabbit hole goes." - Morphius
The red pill and its opposite, the blue pill represent the choice between the blissful ignorance of illusion (blue) and embracing the sometimes painful truth of reality (red). The blue pill would allow them to remain in the fabricated reality of fantasy. The red pill would lead to their awakening harsh reality of the "real world".
Most people took the Blue Pill because for them - "Ignorance is Bliss"
