Obama Campaigns for Biden in Key State of Pennsylvania VOA News Former U.S. President Barack Obama said Wednesday that President Donald Trump is "incapable of taking the job seriously," as Obama campaigned for Democratic candidate Joe Biden in the key state of Pennsylvania. The drive-in rally in the city of Philadelphia was Obama's first in-person event in support of Biden, who served as vice president during his two terms in office. "I never thought Donald Trump would embrace my vision or continue my policies, but I did hope for the sake of the country that he might show some interest in taking the job seriously," Obama told the crowd sitting in nearly 300 cars spread across a stadium parking lot. "But it hasn't happened," Obama said, "He hasn't shown any interest in doing the work or helping anybody but himself and his friends or treating the presidency like a reality show that he can use to get attention." .
