Republican candidate Donald Trump leads Clinton by a margin of 42 percent to 39 percent in Florida, erasing the Democrat's eight-point lead in June, according to the poll conducted by Quinnipiac University.
Sen. Bernie Sanders, I-Vt., accompanied by Democratic presidential candidate Hillary Clinton, speaks during a rally in Portsmouth, N.H., Tuesday, July 12, 2016, where Sanders endorsed Clinton for president.
Quinnipiac also found the candidates in a statistical dead heat in OH - where they are tied at 41 percent - and Pennsylvania, where Trump leads 43 percent to 41 percent. The two were also tied in OH in the university's previous survey.
Although Trump's rhetoric on trade appeals to the wide margin of voters, they still think Clinton is more prepared to be president and more intelligent than the billionaire.
Pennsylvania voters cast their support behind Trump when it comes to job creation, but believe Clinton would be better on immigration.
Quinnipiac surveyed 1,015 Florida voters with a margin of error of 3.1 percentage points; 955 OH voters with a margin of error of 3.2 percentage points; and 982 Pennsylvania voters with a margin of error of 3.1 percentage points. The numbers are similar to the June 21 poll that had them tied at 40 percent. If Trump gives up the documents on or before July 15, Brock said a male Republican philanthropist and political donor - who Brock noted has supported Barry Goldwater, Ronald Reagan, both presidents Bush and the past two Republican presidential nominees - will shell out $5 million to a veteran's charity of the NY businessman's choosing.
While the latest poll might show the two leaders within a margin of error, but it is not seen as a good sign by the Clinton campaign.
Voters in the three swing states overwhelmingly agree with the statement: "The old way of doing things no longer works and we need radical change".
"We know the battlegrounds are going to be close til [l] the end", Brian Fallon, Clinton's national press secretary, said in a tweet Wednesday morning.
Trump, on the other hand, remains a political force from afar. "Although he is winning among white voters, who are mainly Republican, victory in Florida will be a very hard lift for him if he can't do better among non-white voters".
The Reuters/Ipsos poll surveyed 1,146 likely voters across the continental United States, Alaska and Hawaii.
