Twelve years in Congress. Daily conversations with Republican members of Congress. Bipartisan trips abroad with time to talk at length. Work on legislation of mutual interest with members across the aisle that I respected and admired. But those dozen years left me alarmed and frustrated by the inability of Republicans and Democrats to comprehend each other well enough to work together on our country’s major challenges. We share the same titles and vote on the same legislation, but we see the world through dramatically different lenses.
