A new poll of New Hampshire voters has Donald Trump with a commanding lead over the other contenders for the Republican presidential nomination.
The Public Policy Polling survey, conducted from Aug. 21 to 24, has Trump with 35 percent support, more than three times that of second place finisher John Kasich's 11 percent.
Trailing Kasich is Carly Fiorina at 10 percent, Jeb Bush and Scott Walker at 7 percent, Ben Carson at 6 percent and Chris Christie, Ted Cruz and Marco Rubio at 4 percent. Rand Paul received just 3 percent.
Walker has dropped 17 percent from April, when he was leading the field at 24 percent.
On the Democratic side, Bernie Sanders leads the field at 42 percent, followed by Hillary Clinton at 35. Jim Webb received 6 percent, Martin O'Malley 4 percent and Lincoln Chafee 2 percent.
Suffolk University also released a new poll Tuesday of likely Iowa Democratic presidential caucus voters.
The results showed that even though 52 percent of likely voters say the email controversy will hurt Clinton in a general election, she still leads the Democratic field by a wide margin.
The poll had Clinton at 54 percent in Iowa, followed by Sanders at 20 percent and Vice President Joe Biden at 11 percent. Biden hasn't officially entered the race but is said to be seriously thinking about getting in.
"There is a fierce loyalty to Hillary Clinton among likely Democratic caucus-goers in Iowa," said David Paleologos, director of the Suffolk University Political Research Center. "Despite reports suggesting her vulnerability, these Democratic voters say they don't believe she broke the law."
