I believe this because over and over in my six years in office, I have seen America at its best. I've seen the hopeful faces of young graduates from New York to California, and our newest officers at West Point, Annapolis, Colorado Springs, New London. I've mourned with grieving families in Tucson and Newtown, in Boston, in West Texas, and West Virginia. I've watched Americans beat back adversity from the Gulf Coast to the Great Plains, from Midwest assembly lines to the Mid-Atlantic seaboard. I've seen something like gay marriage go from a wedge issue used to drive us apart to a story of freedom across our country, a civil right now legal in states that seven in 10 Americans call home.
