With three days until Election Day, and President Donald Trump and former Vice President Joe Biden racing toward Nov. 3, more than 91 million Americans have already cast their ballots -- an early voting record.

On Saturday, Biden's top surrogate, former President Barack Obama, is joining him for the first time on the trail with drive-in rallies in Flint and Detroit.

Trump has four rallies in Pennsylvania as both candidates plan to "barnstorm" the state they deem critical in the final days before the election with the contest overshadowed by coronavirus cases rising there and in nearly every battleground territory.

Vice President Mike Pence has a pair of rallies in North Carolina -- a state Trump won by four points in 2016. California Sen. Kamala Harris is campaigning in Florida as Democrats vie for the state's 29 electoral votes key to Trump's pathway to the White House.

Trump says Pennsylvania 'will save the American dream'

At the first of his four Saturday rallies in the battleground state of Pennsylvania, President Donald Trump told the crowd, "this is the state that will save the American dream."

"A great red wave ... is forming," Trump said in Bucks County. "And there's not a thing they can do about it."

When Trump brought up Democratic nominee Joe Biden, some in the crowd yelled "lock him up!"

"I fought harder for you than any president," Trump said.

"Nobody has done in three-and-a-half years, nobody, no administration, no president what we've done and what we've accomplished... Nobody even challenges that," Trump said, without mentioning the coronavirus pandemic.

Trump, in a calm, subdued, voice, continued, "Do not be intimidated by our opponent's angry and menacing tone. Because if we were, we would never have been able to accomplish what we've accomplished. In truth, they are actually terrified of you, the people.

Trump later mentioned COVID-19, saying "we're rounding the turn," even though the U.S. on Friday set a new daily case record for the second straight day.

The Bucks County rally was held outside but social distancing was not enforced. Many were seen without masks.

In 2016, Trump narrowly won Pennsylvania by 44,000 votes – less than 1% of the total ballots cast in the state.

Arizona rate of return: 68.1% (as of Oct. 29)
