Former President Barack Obama said President Trump treats the presidency as "one more reality show" in his address on Day 3 of the Democratic National Convention.<br /><br />"I did hope, for the sake of our country, that Donald Trump might show some interest in taking the job seriously," Obama said. "But he never did."<br /><br />He urged Democrats to vote for his former vice president, Joe Biden, saying that democracy is at stake in November's presidential election.<br /><br />"Do not let them take away your power. Don't let them take away your democracy," he said.<br /><br />Obama spoke on Wednesday from Philadelphia, the birthplace of the Constitution, just ahead of remarks by vice presidential nominee Kamala Harris.
