You may not have heard of Dan Morales, and until last week, few had heard of Joel Klein. But you've definitely heard of Ralph Nader. Klein is head of the U.S. Department of Justice's antitrust division.
Morales is the attorney general of Texas.
Both supervise lawyers and investigators who are looking into business practices at Microsoft. Based on the record to date and notwithstanding last week's allegations, government investigations of Microsoft tend to be cause for yawning. When Nader joins the fray, though, something fundamental changes. The consumer activist has made plenty of miscues over the years and carries real baggage. But he's still a household name.
