Glenn Reynolds points to the effectiveness of boycotting Citgo. Citgo supplies gas from Venezuela. Calls for boycotting Citgo began 2 years ago after Chavez spoke at the UN. The words of a tyrant are costly. But it was the actions of Chavez which prompted me more than his words. His brutal tactics against the citizens of Venezuela should not be rewarded.
I never did buy gas from Citgo so boycotting those gas stations were easy. But there are other ways to boycott. When a company needs lubricating oils for machinery, it is easy to to let a buyer know about Chavez and his tyranny. Happily, in my experience, the needed lubricants were not bought from Citgo.
