Washingtonians love to complain about taxation without representation. But for me and my fellow noncitizens, it is a fact of political life that we submit to unquestioningly year after year, primary after primary, presidential election after presidential election. Nearly 15 million people living legally in the United States, most of whom contribute as much as any natural-born American to this country’s civic, cultural and economic life, don’t have a say in matters of politics and policy because we — resident foreign nationals, or “aliens” as we are sometimes called — cannot vote.
