Hillary Clinton leads Donald Trump among likely voters in Pennsylvania and Florida but trails him in Nevada and Arizona, according to CNN polls released Wednesday.

Among likely voters surveyed in Pennsylvania, Clinton leads Trump by 4 percentage points — 48 percent to 44 percent. Libertarian Gary Johnson took 4 percent, and the Green Party’s Jill Stein garnered 1 percent.


In Florida, Clinton also has a slight lead over Trump in a four-way race, garnering 49 percent to his 47 percent.

The news in Nevada is less favorable for Clinton — the survey has her trailing Trump by 6 percentage points among likely voters there, 43 percent to his 49 percent in a four-person field.

In Arizona, a state that's not traditionally in play in presidential years but Clinton has aggressively courted, Trump is ahead by 5 points, capturing 49 percent of likely voters to Clinton's 44 percent.

The surveys were conducted from Oct. 27 to Nov. 1, which means some but not all of the responses came after news related to Clinton’s use of a private email server as secretary of state shook the race. The FBI told congressional leaders Friday that it is reviewing a newly discovered set of emails that may or may not be significant to its previously concluded investigation into Clinton’s email server, and the revelation dominated weekend news cycles.

The surveys, which had a margin of error of 3.5 percentage points, also asked likely voters about their preferences in each of the four states’ Senate races.

In the three more competitive races, Republicans led by a small margin in two states — Nevada and Florida — and trailed in Pennsylvania.

In Nevada, the survey found that Republican Rep. Joe Heck leads Democratic former state Attorney General Catherine Cortez Masto among likely voters by 2 points, 49 percent to 47 percent. In Florida, Republican Sen. Marco Rubio leads his Democratic challenger, Rep. Patrick Murphy, by just 1 point, according to the survey. Rubio had the support of 49 percent of surveyed likely voters, while Murphy took 48 percent.

The survey was better news for Democrats’ Senate hopes in Pennsylvania, where Katie McGinty is challenging Republican Sen. Pat Toomey for his seat. McGinty received support from 51 percent of surveyed likely voters in the poll, while Toomey got 46 percent.

Incumbent Sen. John McCain, whose Arizona seat is not widely viewed as in play, had a double-digit lead over his Democratic challenger, Rep. Ann Kirkpatrick, in the poll. Fifty-four percent of likely Arizona voters surveyed said they support their current senator, while 41 percent indicated that they support Kirkpatrick.
