Donald Trump, Hillary Clinton Make Final Pitch to Voters

Donald Trump and Hillary Clinton each woke up Saturday in Florida, the biggest prize on the presidential battleground, as they worked to turn out their supporters in a final sprint to Election Day. 

At this point, the primary goal is less to win over new voters and more to motivate their own supporters to show up at the polls. In battleground states across the country this weekend, volunteers will be making phone calls and knocking on doors, TV watchers will see a final burst of ads, and the candidates will travel thousands of miles in a last round of campaigning. 

Democratic nominee Hillary Clinton is scheduled to appear at an afternoon rally in the Miami area before flying to Philadelphia, where she is set to share the stage with pop singer Katy Perry, the latest in a string of concerts aimed at moving young people to the polls. 

Her campaign said some one million volunteers would go house to house and make calls over the final stretch. Republican Donald Trump's campaign is relying mostly on the Republican National Committee to reach out to individual voters, with a ground game generally seen as far less sophisticated. 

Mr. Trump is campaigning in the Tampa area first thing on Saturday and then planned to jet to North Carolina and Nevada before ending the day in Colorado. In all, he was scheduled to visit at least nine states, maybe more, on the Friday-to-Sunday stretch. That includes places where he's leading such as Iowa, tossups like Florida, and states thought to be safely Democratic, such as Wisconsin. 

Mrs. Clinton plans to campaign in five states over the same three-day period, including events all three days in Pennsylvania, a firewall state that tilts her way and where a win would block many of Mr. Trump's possible paths to victory in the Electoral College. 

Locking down Democratic-leaning states is essential for Mrs. Clinton, who can win the race if the states leaning her direction come through -- even if she loses most of the traditional battlegrounds. "Her priority is to focus on her firewall," said Chris Kofinis, a Democratic strategist. 

Both campaigns see hopeful signs in early votes already cast, with each side cherry-picking statistics to make their cases. But in Pennsylvania and Michigan, where Mrs. Clinton campaigned Friday, nearly all the votes are cast on Election Day, so the campaigns face a bigger turnout challenge. 

Mrs. Clinton is getting high-powered help. President Barack Obama, Vice President Joe Biden, Vermont Sen. Bernie Sanders and others are campaigning for her this weekend. On Sunday, NBA star forward LeBron James will appear by her side in Cleveland, a rare showing on the trail for Mr. James. 

On Friday night, there was more star power in Cleveland, as Mrs. Clinton turned to Beyoncé and Jay Z. The singer and her rapper husband performed at a get-out-the-vote concert, urging a raucous crowd to help make history on Election Day. 

Beyoncé and her backup dancers donned pantsuits -- a Clinton wardrobe staple -- for the occasion. 

"I am so energized after this concert," Mrs. Clinton said. "I've got to say: Didn't you love the pantsuits?" 

Clinton aides had said their aim was to end the race with a unifying spirit in hopes of laying the foundation for her to better govern if elected. They emphasized her outreach to Republicans, announced plans to campaign in Arizona, traditionally a Republican state, and suggested she might be able to win Utah, too. They released a TV ad dubbed their "closing argument" featuring Mrs. Clinton talking about her commitment to children and families. 

But those goals largely fell away a week ago, after the surprise FBI announcement that investigators had found additional emails from Mrs. Clinton's family server on the laptop of one of her aide's estranged husband. It wasn't clear whether these emails are incriminating, but the news dominated the campaign conversation. 

Mr. Trump has made the FBI disclosure central to his final pitch to voters. Mrs. Clinton replied by trying to revive discussion of what voters don't like about Mr. Trump. 

"If she were to win it would create an unprecedented constitutional crisis," Mr. Trump said in New Hampshire on Friday. 

In Detroit on Friday, Mrs. Clinton said: "Imagine having a president who demeans women and mocks the disabled, who insults African-Americans and Latinos and Muslims, who personally engages in busting unions and preventing people from having the right to bargain collectively," she said. 

One question is whether this weekend either or both of them would pivot to a more optimistic tone. Typically, presidential candidates try to close out their runs with a positive message aimed at making voters feel good about voting for them. But this year's election has defied all precedents. 

"The attacks work. Why stop what's working," said Dave Carney, a New Hampshire-based Republican strategist who backs Mr. Trump. "Time is short. They need to paste the other with the best negatives they've got."
