2020 Watch: Democrats begin their all-virtual convention

The first national political convention of the coronavirus era has arrived. For four consecutive nights beginning on Monday, Democrats from across the country will gather — in front of their computers, television screens and smart phones — for the all-virtual affair that will showcase the diversity of the modern-day Democratic Party and test Joe Biden's ability to energize his sprawling coalition. President Donald Trump is working to step on the Democrats' convention — and prevent Biden from earning any convention polling bounce.
