Karin Caifa: Can Joe Biden unite America?

President-elect Joe Biden's victory over President Donald Trump sparked celebrations in cities across the country, including many of the places that swept Biden into the White House.
From New York to Miami in the East and Denver and Austin out West, Biden supporters flooded into the streets after CNN and other news organizations projected Biden as the winner Saturday morning, honking horns, cheering, dancing and popping champagne.
In Washington, DC, a crowd packed into the streets in front of the White House at Black Lives Matter Plaza, within seconds of the race being called. The streets nearby filled with people shouting, banging pots and pans, and singing, "Nah nah nah nah, hey hey hey, goodbye."
The celebratory crowd in the blocks around the White House created a traffic jam, with people sitting on top of cars and drivers holding their fists out the window. One person wearing an American flag as a cape walked toward Black Lives Matter Plaza with a hand-written posterboard that read, "The nightmare is over."
The packed crowd outside the White House later sung "YMCA," the song Trump used to close out his rallies down the homestretch of the campaign.
Trump, however, was not at the White House on Saturday morning -- he was at his golfing at his club in Virginia when CNN and other networks called the race.
Both Biden and Trump supporters gathered at the club's entrance and lined the road leading up to it. "You're fired," read the sign of one Biden backer. Vehicles with Trump flags drove back and forth, and one person shouted, "Media sucks."
In Philadelphia, which was key to Biden's decisive Pennsylvania win, cars honked, people waved Biden flags and a large crowd gathered outside of Philadelphia's City Hall. It was unseasonably warm, and people were pouring into the streets with everything from coffees to brunch cocktails. Most were wearing masks.
"Biden town!" a woman yelled out of a car headed down Broad Street in the city's downtown area. There was a constant stream of cars driving by honking, with people fist-pumping out the windows.
People took turns taking their picture under a "Good Things Happen in Philadelphia" banner.
Chris Halt, his wife Deb and their dogs Jelly and Donut were driving through the city in an old Volkswagen bus with a Biden sign hanging off the car. "People were saying it's a peaceful protest. No, this is a joyous celebration,' Chris Halt said.
Robert Nunez, riding in his car with his family, stood through the sunroof yelling in celebration. "The four-year nightmare is over," said Nunez, who said he cried when he found out the Trump presidency was coming to an end.
Adrienne Register, a school psychologist from New Jersey, and her 16-year-old daughter, Arianna, joined the celebration outside City Hall in downtown Philadelphia. She said she remembers the exact time -- 11:26 a.m. -- that a friend texted her to tell her the news.
"We're ecstatic," Register said. "It's been a scary few days."
The crowd that gathered outside City Hall began marching in the direction of Independence Hall, where the Declaration of Independence and Constitution were signed.
"We're just really excited about a new transition in the country," said Beth Lapiene, a Temple University law school student who was among the revelers outside of City Hall in Philadelphia. "We're really excited about Kamala Harris."
She said the last few days of waiting for results were "anxiety-provoking" and she didn't get a lot of school work done.
Her fellow law student, Daniel Gordon, 24, chimed in, "I was praying not to get cold-called in class."
A chorus of horns filled Broad Street, right outside of the Pennsylvania Convention Center. As morning turned into afternoon, the once quiet street, which only saw occasional joggers and people going for coffee or bunch was soon filled with horns and groups of people erupting in cheers.
"I'm so happy. I don't...
