Hillary Clinton has bounced to small leads over Donald Trump in Florida and Ohio and a double-digit edge in Pennsylvania, according to Quinnipiac University polls released Tuesday.

The polls — Quinnipiac’s first measures of "likely voters" this election cycle as opposed to all "registered voters" as it had in past surveys — show Clinton running neck-and-neck with Donald Trump in Florida, with the Democratic presidential nominee ahead 46 percent to 45 percent. Clinton’s lead is slightly larger in Ohio, with the former secretary of state ahead 49 percent to 45 percent. In Pennsylvania, Clinton leads by 10 points, 52 percent to 42 percent.

Clinton’s lead shrinks slightly when Gary Johnson and Jill Stein — nominees of the Libertarian Party and Green Party, respectively — are included, though neither third-party candidate earns more than 8 percent in any of the states. Clinton and Trump are tied at 43 percent in Florida on a four-way ballot, and Clinton leads by 2 points in Ohio and 9 points in Pennsylvania.

Quinnipiac said in a news release that the new polls should not be compared with previous surveys of all registered voters, but it is worth noting that its past polls had been more positive for Trump than other surveys. Last month, Quinnipiac found Trump ahead in both Florida and Pennsylvania among registered voters, and the two candidates deadlocked in Ohio.

The new polls were conducted July 30 to Aug. 7 — a relatively long time in the field. Quinnipiac surveyed 1,056 likely voters in Florida, 812 likely voters in Ohio and 815 likely voters in Pennsylvania; the margin of error is plus or minus 3 percentage points in Florida, and 3.4 percentage points in both Ohio and Pennsylvania.
