From the “Hope and Change” rhetoric of 2008, Barack Obama has modified his theme to “Divide and Conquer,” but he hasn’t put it on a bumper sticker. In fact, he hasn’t mentioned it once. I guess he’s hoping the rest of us won’t notice. But for the past four years, this president has either blamed his predecessor, President George W. Bush, for his woes, or practiced class warfare par excellence. He has pitted different segments of society against others, as he cleverly demonized one side in an effort to gain support from the other.
