Joe Biden pondered a most serious, and awkward, question at a campaign stop Friday: What if Barack Obama had been assassinated during his presidential campaign in 2008? Toward the end of an event in Hanover, Biden evoked two of his political heroes, Martin Luther King Jr. and Robert F. Kennedy. Both were assassinated in 1968, Kennedy while running for president.
