In a video presentation, NationalJournal.com's Theresa Poulson examines the role that abortion could play in Sonia Sotomayor's confirmation hearings, and how this debate could unfold in the future if she is confirmed.

(This is the first in a series of four videos examining key players in Sotomayor's hearings. The series will also look at the role of the White House, conservative interest groups and senators.)
