Obama to Be America's First Black Presidential Nominee

AP reports: "Sen. Barack Obama of Illinois sealed the Democratic presidential nomination Tuesday, a historic step toward his once-improbable goal of becoming the nation's first black president."

I echo what Rich Lowry wrote earlier this afternoon:

Even if we're going to hear it over and over, it's true—this is a historic moment. That an African-American has a better than even chance to be the next president of the United States is an amazing thing—and heartening about this country's capacity for progress.

I've made no secret of my disagreement with Sen. Obama's politics, especially his vision for how the will of the powerful trumps the rights of the weakest and most defenseless members of the human race. Even with this disappointment, today is a significant day in American history--virtually unthinkable a generation ago.
