Fifty years ago, the nation was still reeling with the news President Kennedy had been gunned down in Texas.

Over the last half century, experts and others have wondered what the world would be like if Kennedy wasn't killed.

Former New Bedford Mayor Scott Lang says while nobody can be certain what the impact would have been, it's clear what Kennedy meant when he said "ask what you can do for your country"....

Lang was active in Senator Ted Kennedy's Presidential Campaign in 1980, and worked with him many times as both of their political careers progressed.
