Thankfully, the twentieth GOP presidential debate has come and gone. If the American voter doesn’t know these candidates by now, he never will. Of the four remaining candidates, three are virtually indistinguishable from one another. This much has been established time and time again throughout this election season. It is true, of course, that there exist some differences between Mitt Romney, Rick Santorum, and Newt Gingrich. But such differences are negligible, both in themselves and, especially, relative to the enormity of the similarities that they share.
