Gary Becker has problems with Lou Dobbs too. From the Becker-Posner Blog:

I instinctively am dubious about the legitimacy of the opposition to the Dubai Ports World transaction when it is led by the new Lou Dobbs, the CNN business commentator, who saved his sinking ratings by discovering that he never met any imports to the United States that he likes, whether of goods, services, or people. He may by accident be right in the Dubai ports situation, but his opposition makes me suspicious of the motives behind much of the more vocal opposition.
