Trump leads former Hewlett Packard CEO Carly Fiorina among potential New Hampshire GOP primary voters by just 5 points, 21 to 16 percent, according to NBC News/Wall Street Journal/Marist pollsters.
Trump and Fiorina are trailed by former Florida Gov. Jeb Bush with 11 percent and Sen. Marco Rubio (Fla.) and retired pediatric neurosurgeon Ben Carson with 10 percent apiece.
In September, Trump led Ohio Gov. John Kasich, his closest competitor at the time in New Hampshire, by 16 points, 28 to 12 percent.
In Iowa, Trump now leads Carson by 5 points, 24 to 19 percent. Fiorina follows with 8 percent, Bush with 7 percent and Sen. Ted Cruz (Texas), Rubio and Louisiana Gov. Bobby Jindal with 6 percent each.
One month ago, Trump led Carson by 7 points in the Hawkeye State, 29 to 22 percent.
Among Democrats, Hillary Clinton maintains her lead among potential Iowa Democratic caucus-goers and Sen. Bernie Sanders (I-V.) is still the leader among potential New Hampshire Democratic primary voters.
Clinton leads Sanders by 11 points, 47 to 36 percent in Iowa. Former Maryland Gov. Martin O’Malley has 4 percent. Clinton’s lead in the Hawkeye State is only 5 points when Vice President Joe Biden is added to the field, however.
Sanders leads Clinton by 9 points, 48 percent to 39 percent, in New Hampshire in results that are virtually unchanged from a month ago. Biden gets 18 percent when added to the equation, while support for Sanders falls to 42 percent and Clinton gets 28 percent.
The NBC/WSJ/Marist polls were conducted Sept. 23-30. They have a 4.7 percent margin of error for potential Iowa GOP caucus-goers and a 5.3 percent margin of error for Democrats. In New Hampshire, their margin of error is 4.6 percent for potential GOP primary voters and 4.9 percent for Democrats.
