A virtual four-way tie exists among the leading 2016 Republican presidential contenders in the latest primary poll, released Tuesday.
The Public Policy Polling survey
showed New Jersey Gov. Chris Christie and Kentucky Sen. Rand Paul each with 16 percent, followed by Texas Sen. Ted Cruz and former Florida Gov. Jeb Bush with 14 percent each.
"The biggest change compared to a month ago is a 5-point decline in Cruz's support from its peak in the immediate aftermath of his long speech on the Senate floor," the polling analysis said, adding that Bush saw a 3-point increase in his support and Christie a two-point bump.
Paul was within a point of where he was in the last survey, the analysis showed.
The ideological splits in support are "massive," however, the analysis showed.
Among voters identifying as "very conservative," Christie had 3 percent and Cruz led with 26 percent, followed by Paul at 18 percent and Bush with 15 percent.
Among moderates, Christie pulled in 18 percent while Cruz got only 5 percent; Bush polled at 18 percent, and Paul had 10 percent.
On the Democratic side, former Secretary of State Hillary Clinton was dominant, the poll showed, with 67 percent of primary voters behind her for a run in 2016. The poll showed 12 percent supported Vice President Joe Biden.
Clinton dominates in the match-up against Republicans by at least 5 points, polling showed. Christie comes closest at 44 percent to 39 percent, followed by Bush at 48-39 and Paul at 49-37. Clinton leads Cruz 50 percent to 33 percent.
Biden trails Christie 45 percent to 38 percent, and trails Bush by 43-42. Biden leads Paul 45-38 and Cruz 46-36, the poll showed.
The poll's overall margin of error is 3.8 percentage points.
