As a proud Republican, casting my vote for President has usually been a simple matter. This year is different. To vote Republican out of party loyalty alone would be to endorse a candidacy that I believe has exploited anger, grievance, xenophobia and racial division. Donald Trump’s demagoguery has undermined the fabric of our national character.

Trump’s reckless and uninformed positions on critical issues — from immigration to our economy and foreign policy — have made it abundantly clear that he lacks both the policy depth and sound judgment required as President. Trump’s unsteady hand would endanger our prosperity and national security. His authoritarian character could threaten much more.

Therefore, I have decided to support Hillary Rodham Clinton. It is clear to me that Secretary Clinton’s temperament, global experience and commitment to America’s bedrock national values would make her the far better choice in 2016 for President of the United States. In a tumultuous world, America needs the kind of stable and aspirational leadership Secretary Clinton can provide. I urge all Republicans to reject Donald Trump this November.
