While voters across New Hampshire make their picks in the first-in-the-nation primary vote, Republican presidential candidate Ben Carson told Fox Business Network host Neil Cavuto he is "open" to being Donald Trump's vice-presidential pick. "I certainly would sit down and discuss it with him," Carson said of Trump, who currently leads the polls in New Hampshire. Carson, while still in the primary race, has consistently polled below five percent in the state and plans on missing his own campaign party Tuesday evening.
