President Obama appeared on Late Night The Late Show with David Letterman and repeated his belief that the political opponents were not primarily motivated by his skin color:
It was classic David Letterman — acerbic in a fun way — and vintage Barack Obama — charmingly modest.
Asked about Jimmy Carter’s charge that opposition to Obama health care reform is rooted in racism, Obama said, “I was actually black before the election.” Attributing the criticism to the heat of the issues, the president noted that FDR was reviled as a socialist, Ronald Reagan as a reactionary.
“This is not untypical,” he said. “One of the things you sign up for in politics is folks yell at you.”
Here’s the video:
Now, can we all stop talking about racism.

Minor correction: it’s the Late Show With David Letterman, not Late Night. (Been then way since 1994, yet people constantly make this mistake. Heh.)
yea I keep making that mistake
