We've had a 10-car pileup of failure and crisis, going back to the Bush years, the 9/11 attacks, the war in Iraq, the federal response to Hurricane Katrina, the mortgage crisis and the Great Recession. A particularly extreme brand of partisanship developed after Obama's election and over Obamacare; it deepened with the 2010 midterms, leading to a partial government shutdown last year. Add the flood of refugees, many of them unaccompanied minors, at the U.S.-Mexico border. Add the rise of Islamic State militants. Add the outbreak of Ebola and its arrival here. And, under all of that, we have the constant ridicule and rejection of government. No wonder a majority of Americans have lost faith in the system and in the big promise of an exceptional society.
