David Gergen wrote a wonderful piece on Barack Obama's nomination of Judge Sonya Sotomayor, and what really means:
To watch the first African-American President from a broken family promote to the U.S. Supreme Court an Hispanic woman from a broken neighborhood was one of those moments that Americans will long savor. In his announcement today of his first nominee to the Court, President Obama quickly brought back memories of why the country elected him.
I was in the White House in 1981 when President Reagan nominated Sandra Day O’Connor as the first woman to join the Court, and I can remember greeting her in Chief of Staff Jim Baker’s office just before the announcement. It was Reagan’s first nomination, too – a highly symbolic occasion – and enormous pride flowed through every one of us present that day.
President Obama’s announcement stirred those same, overwhelming feelings. It is said that a president campaigns in poetry and governs in prose. Today was almost all poetry. It is likely to be remembered as one of the President’s finest hours.
