 In the wake of President Biden's poor debate performance in June, an APNORC Center for Public Affairs research poll shows some mixed results about Vice President Kamala Harris becoming president. Correspondent Donna Warder reports. The survey found that about 6 in 10 Democrats believe Vice President Kamala Harris would do a good job as president. About 2 in 10 Democrats don't believe she would. And another 2 in 10 say they don't know enough to say.
