Patrick Kennedy, D-R.I., listen to President Barack Obama's speech on healthcare before a joint session of Congress on Capitol Hill in Washington. The late Sen. Edward Kennedy will be a tough act to follow, even for the Kennedys. Kennedy's brain-cancer death, coupled with the decision by family members not to seek the seat he held for nearly five decades, has prompted plenty of speculation that the family's long-running political dynasty is over.

US Senate Majority Leader Harry Reid of Nevada speaks to the press after the Senate, torn along party lines, voted to formally launch debate on historic legislation to enact President Barack Obama's signature drive to remake US health care, handing him a win for now, in Washington, DC, on November 21, 2009. The 100-seat chamber's two independents joined all 58 Democrats -- including two waverers who declared their intentions just hours earlier -- to launch what is expected to be a weeks-long fight over opposition from 39 of 40 Republicans.
