Speaking at a drive-in event in Philadelphia, Obama said with Biden and Harris in the White House, Americans are “not going to have to think about the crazy things they said every day.”
“And that’s worth a lot,” Obama said Wednesday. “You’re not going to have to argue about them every day. It just won’t be so exhausting.”
Obama said that over the past four years, Americans “have had to live with the consequences of him [Trump] proving himself incapable of taking the job seriously.”
“I never thought Donald Trump would embrace my vision or continue my polices, but I did hope for the sake of the country, that he might show some interest in taking the job seriously," he said.
"But it hasn't happened. He hasn't showed any interest in doing the work or helping anybody but himself and his friends,” Obama added.
Obama also issued a stark reminder of 2016, when opinion polls showed Hillary Clinton as the clear favorite -- only for her and her supporters to be shocked by a Trump victory on Election Day.
"We can't be complacent. I don't care about the polls," the former two-term president told the rally outside a baseball stadium.
"There were a whole bunch of polls last time. Didn't work out. Because a whole bunch of folks stayed at home. And got lazy and complacent. Not this time. Not in this election."
He told supporters that too much was at stake to have four more years of Trump leading the nation.
Obama warned that “the next 13 days will matter for decades to come.”
