Age: 48
Title: President and CEO, Dale Earnhardt Inc.
Pro: Helped her late husband build his business from scratch. In the aftermath of the Intimidator's 2001 death, Earnhardt brokered new licensing and sponsorship deals, growing the company when many thought it might collapse.
Con: Long-standing power struggle with her stepson, Dale Earnhardt Jr., ended with DEI's most valuable chip walking away from his late-father's company. Maybe Teresa never should have pushed Dale Jr. into military school when he was a teen.
