"Nikki Haley Gains Ground in GOP Race, Trump's Lead in Question"

Steve Kornacki draws parallels between the current Republican presidential race and the 2000 primary season, highlighting the potential challenge former United Nations Ambassador Nikki Haley poses to Donald Trump in New Hampshire, similar to John McCain's threat to George W. Bush. He emphasizes the significance of independent voters in New Hampshire and the cautionary tale of McCain's loss in South Carolina due to a lack of support from Republican loyalists, suggesting that a victory for Haley fueled by non-Republicans could be viewed with suspicion by Republicans elsewhere.
