Ted Kennedy famously considered health care reform the "unfinished business" of America. Yesterday, son Patrick visited his Arlington gravesite and left a simple note: "Dad, the unfinished business is done," reports the Washington Post. A steady stream of visitors has been at the tombstone since the weekend. Ted's widow, Vicki, spent hours there on Sunday before taking a place of honor at today's signing. 
                                    
                                    
                                
                                
                             
                            
                            
                            
                            
                            
                                
                                
                                    
                                        President Obama also paid homage. "I remember seeing Ted walk through that door in a summit in this room a year ago, one of his last public appearances, and it was hard for him to make it, but he was confident that we would do the right thing."
