Donald Trump’s lead among Republicans nationally has soared back to double digits, according to the results of the latest Quinnipiac University poll released Wednesday, while on the Democratic side, Hillary Clinton and Bernie Sanders are locked in a virtual tie.

Trump grabbed 39 percent, up 8 percentage points from the previous two weeks, followed by Florida Sen. Marco Rubio at 19 percent, whose numbers were unchanged. Texas Sen. Ted Cruz dropped 4 points to third place with 18 percent, and Ohio Gov. John Kasich was fourth at 6 percent. No other candidate polled above the margin of error, and 9 percent were undecided.


The Manhattan businessman is also perceived as the party’s best candidate to win in November, with 77 percent of those surveyed responding that he has a good chance of winning in the general election compared with 61 percent for Rubio and 60 percent for Cruz.

Among Democrats, Clinton took 44 percent to Sanders’ 42 percent, as that race continues to tighten ahead of contests in Nevada and South Carolina. The gender gap between the candidates is shrinking, with women supporting Clinton over Sanders 47 percent to 41 percent and men backing Sanders over Clinton 44 percent to 40 percent.

While 83 percent of Democrats said Clinton would have a good chance of winning in November, a smaller share — 69 percent — said the same for Sanders.

The poll was conducted Feb. 10-15, surveying 1,342 registered voters nationwide via landlines and cellphones with an overall margin of error of plus or minus 2.7 percentage points. The sample includes 602 Republican voters with a margin of error of plus or minus 4 percentage points and 563 Democrats with a margin of error of plus or minus 4.1 percentage points.
