Many moons ago, I thought well of Tucker Carlson. We occasionally jousted on CNN’s "Crossfire," when I was a guest host. In those days, Carlson presented himself as a committed journalist. He played on the conservative field, but he insisted he prized accurate reporting. He told me his goal was to differentiate himself from many of the writers for right-wing media and not be seen as an ideological hack. And he demonstrated that with a profile he did of George W. Bush in 1999 for Tina Brown’s Talk magazine.
