Clinton and Obama likely to end up at the mercy of party powerbrokers
Both Jack and Barack were Harvard educated, but the big parallel is that Obama is trying to become the first black president, whereas Kennedy was the first Roman Catholic elected to the White House.
Whatever happens, it looks like it will be a first for the Democratic party this year because it will be the first major party to nominate either a black or a woman for president. This adds an incalculable factor to analysing what is likely to happen.
