For democrats who chose him during his primaries, his #1 quality was that he was a moderate/centrist. The democrat party isn't only made up of leftists/progressives. There were a considerable number of democrats who were scared of Bernie and turned off by his supporters. For GOP/Independents who voted Biden, his #1 quality was also that he was moderate and a close second was that he was not divisive.
