U.S. Sen. Elizabeth Dole also ranks poorly compared to the rest of her class.

Of the nine senators elected in 2002 still in office, Dole is ranked eighth in power rankings put together by the nonpartisan Congressional data company Knowlegis.

Here's the ranks of her classmates:

Lamar Alexander: 32nd
Lindsey Graham: 60th
Saxby Chambliss: 61st
Mark Pryor: 62nd
John Cornyn: 80th
Norm Coleman: 82nd
John Sununu: 89th
Elizabeth Dole: 93rd
Lisa Murkowski: 96th

Except for Pryor, all of Dole's 2002 classmates are Republicans.

Knowlegis cofounder Brad Fitch said that comparing senators to others who took office in the same year is the best way to gauge their power, since seniority gives senators more power.
