Washington - Barack Obama insists that he doesn't want to get ahead of himself, but a growing number of prominent Democrats and newspaper editorials have suggested it may be time for rival candidate Hillary Clinton to make a graceful exit.
A litany of US media outlets reported Thursday that the "math" just wasn't there anymore for Clinton to capture the Democratic Party's presidential nomination, after she lost badly in North Carolina and barely won Indiana in the latest round of primary elections earlier this week.
