The polls giveth, the polls taketh away. And sometimes it happens in reverse.
It was only two weeks ago that Republican presidential nominee Donald Trump publicly wondered, during a radio interview with conservative host Mike Gallagher, why he wasn't faring better in polls. Since then, a Rasmussen Reports poll put the real estate billionaire two points ahead of Democratic rival Hillary Clinton, and a poll by McClatchy/Marist showed Clinton's lead narrowing over the presumptive Republican nominee.
On July 13, a new poll brought more good news for Trump, showing him ahead of or tied with Clinton in three key battleground states.
The Quinnipiac University Swing State Poll found the former reality TV star leading Clinton 42 percent to 39 percent in Florida, as seen on Real Clear Politics. Trump holds a similarly slim but promising lead in Ohio, according to Quinnipiac, which says he's up 43 percent to 41 percent in that state.
And the candidates are in a tie among Pennsylvania voters, who were split with 41 percent of respondents supporting each of them.
The Quinnipiac survey is one of just a handful of new polls that queried voters in the wake of FBI Director James Comey's recommendation not to file criminal charges against Clinton in relation to her email scandal, which has dogged her campaign for more than a year.
While Comey said there wasn't evidence of intentional criminal wrongdoing, he chided Clinton and her team for being "extremely careless" with their handling of classified information, and refuted several claims Clinton had made during interviews. In particular, Comey said it was likely that hackers had accessed the server, and said that contrary to Clinton's claims, there were more than 100 emails marked classified among the trove still on her server.
While Clinton's team was relieved that the Department of Justice would not file charges and issued a statement saying the matter is "closed," analysts said the saga was another blow to the credibility of a candidate who already had trust issues with the voting public.
"While there is no definite link between Clinton's drop in Florida and the U.S. Justice Department decision not to prosecute her for her handling of emails, she has lost ground to Trump on questions which measure moral standards and honesty," said Peter A. Brown, assistant director of the Quinnipiac University Poll.
For their part, Clinton's campaign staffers acknowledged the tight races in key states, and said they aren't underestimating the Republican presidential hopeful.
"We know the battlegrounds are going to be close til the end. That's why we need to keep working so hard," Clinton press secretary Brian Fallon tweeted July 13. "Trump is a serious danger, folks."
