Joe Biden is running against an unpopular president who gets poor marks from the public on the most important challenges of the day, principally the coronavirus pandemic and race relations. So unsurprisingly, much of tonight's program featured Democratic leaders and regular people attacking Trump on his shortcomings. But importantly, they did spend a fair bit of time trying to reinforce the idea that Biden is the right person with the right attitude to take over the job of president. From anecdotes about his empathy to a segment on the people he met and befriended while riding Amtrak to Washington, D.C., the convention attempted to shore up confidence in Biden, and not just generate anger toward Trump.
