Clinton’s new 60-second ad features Katy Perry’s hit song “Roar” — which has become an anthem for the campaign. The candidate never speaks in the spot, but archival images from her previous government roles play on screen.

After Clinton held a formidable lead for weeks, polls tightened across the country and left both campaigns darting between states in response to the shifting threats and opportunities. The Clinton campaign was suddenly defining typically Democratic places like Michigan and Wisconsin as “battlegrounds.”

WASHINGTON — Hillary Clinton, trying to finish her campaign with a positive message, released a round of inspirational ads in 11 battleground states Saturday as Donald Trump planned trips to traditionally Democratic territory looking for his path to the presidency.


On Monday, the campaign said it will release a two-minute long spot outlining what her campaign hopes will be a “positive and unifying message with the entire country,” according to a Clinton campaign official. The spot, they hope, will be viewed by 20 million on the eve of the election.

Democrats have become concerned that Clinton’s mostly negative campaign aimed at painting Trump as a grave threat to the nation will leave her without a mandate to govern should she win on Tuesday.

“It would have been great to be more positive,” said Democratic strategist Tad Devine. “You want to point to the future; winning campaigns are always about the future.”

But, he added, he can’t fault the Clinton team for its avalanche of negativity in the past week, as it has sought to halt Trump’s rebound in the polls. Trump surged after the FBI revived a criminal investigation into her use of a private server while she was secretary of state.

“The most positive note they can end on is 270 electoral votes,” Devine said. “It is not a time to do anything other than winning.”


Trump’s campaign released its closing campaign spot on Friday, an ad painting Trump as the leader of a movement capable of changing Washington.

“The only thing that can stop this corrupt machine is you,” Trump says in the ad, which is running in nine states. “The only force strong enough to save our country is us.”

During a Trump rally in Reno on Saturday night, a disturbance broke out close to the podium and the candidate was rushed off the stage by Secret Service agents, the Associated Press reported. He returned within minutes and resumed his speech.

The nature of the disturbance was unclear, but security officials escorted a man out of the area soon afterward. Witnesses said the man did not appear to have a weapon.

Trump thanked the Secret Service and told the crowd: ‘‘Nobody said it was going to be easy for us. But we will never be stopped. Never ever be stopped.’’

Trump outlined a hectic schedule in these final days, announcing a stop in Michigan, which hasn’t voted Republican since 1988. He also plans a rally in Minnesota, which has supported only Democratic candidates since 1972. Clinton leads in both states.

“We’re going into what they used to call Democrat strongholds where we’re now either tied or leading,” Trump said.

Both candidates started Saturday with rallies in Florida — a state Trump must win to have a reasonable chance at capturing the presidency. Polls show the race there to be a virtual tie.


Clinton’s speech, at a rally in South Florida, was cut short after only seven minutes due to a heavy downpour. “You’re a hardy bunch,” she said, asking supporters to “vote for the future.”

In Tampa, her opponent had better weather and made a similar argument.

‘‘Hillary Clinton is the candidate of yesterday,” Trump said at the Florida State Fairgrounds in Tampa. “We are the movement of the future.’’

He attacked Clinton’s stamina, suggesting that she spends too much time resting.

‘‘You need energy,’’ Trump said. ‘‘She goes home and she goes to sleep.’’

Clinton’s team has pushed back aggressively on the accusation that she’s easily fatigued, and frequently shares photos on social media of their candidate attending late-night concerts given by some of the many musical stars who are supporting her.

On Friday night, for example, Clinton appeared with Jay Z and Beyonce at a get-out-the-vote concert in Ohio.

Beyonce’s backup singers and dancers wore pantsuits, in homage to Clinton’s preferred attire. As Beyonce performed, Clinton’s controversial “cookies” quote from 1992 flashed on the screen.

The full quote, which caused a huge debate when she said it, seems tame by today’s standards: “I suppose I could have stayed home and baked cookies and had teas, but what I decided to do was fulfill my profession, which I entered before my husband was in public life,” Clinton said when her husband was running for president.

In Pennsylvania later Saturday, Clinton wooed voters with a free performance by pop star Katy Perry.


Clinton told the a crowd at Philadelphia’s Mann Center that it’s ‘‘all on the line’’ on Election Day.

Perry, who has been a big supporter of Clinton, took the stage to the song ‘‘Nasty.’’ She performed her song ‘‘Roar,’’ which has become an anthem for the Democrat’s campaign.

Trump mocked Clinton’s high-wattage night.

‘‘We don’t need Jay Z to fill up arenas,” Trump said in Tampa. “We do it the old-fashioned way, folks.”

The Republican campaign took steps toward party unity Saturday when House Speaker Paul Ryan appeared at a rally with Trump’s running mate, Mike Pence. Both men pleaded with Republicans to “come home” and vote for the GOP.
