Barack Obama is the greatest threat.
Or perhaps since there is no effort to remove him, complacency is the greatest threat.
Had complacency not already taken over you would never have heard of him. So, yes, complacency, along with willful ignorance of the voting population, is the greatest enemy we face. Much of America will believe almost anything as long as it bears no relationship to the observable reality. Many old sayings that I grew up hearing in South Carolina have fallen out of usage. One of those sayings is, “The truth is welcome.”
