For all the fine talk against tribal alliances and calculation in electoral politics, I am yet to see where this is not done in the world.
Recently, Obama won the US elections through a ‘coalition’ that included Blacks, Hispanics and Asians, all of which are ethnic/racial groups. Mitt Romney swept the white vote, also another distinct ethnic bloc. Democracy being about numbers, it would take a miracle of hurricane size for a political leader to win a national election while ignoring the single largest electoral unit, which is the tribe.
