“What makes the partisanship so debilitating is that it's not confined to one party and, despite what so many pundits say, it's much more than a political tool to win elections. It has shaped our culture and our national dialogue. We've lost our ability to disagree without being disagreeable, and to argue substance without questioning the basic decency of the people on the other side of the line. The partisanship rips at the bonds of affection that tie the country state to state, political party to political party, citizen to citizen.”
