 But the reality is there is no way to swap out their party's nominee at this stage unless Biden himself steps aside. Delaware Senator Chris Coons is a national co-chair for the Biden-Harris campaign and told ABC's Jonathan Karl that Biden actually gained support after the debate. The polling I've seen after the debate has actually moved in the direction of Joe Biden. So I do think it's for Joe Biden to make any decision about his campaign, his debate prep, his path forward.
