As first lady, Clinton's signature policy initiative, reforming the nation's health care system, fell apart, largely due to both Clintons' refusal to compromise with health care industry skeptics, and lawmakers. Now campaigning for the presidency in 2008, Clinton says she learned important lessons, and plans a more inclusive approach to reforming health care. (AP Photo/Greg Gibson, File)
