The Biden campaign has long said their easiest path to the nomination hinges on the "blue wall" – Michigan, Wisconsin and Pennsylvania – and that is still a belief that stands tonight.
Even as the race remains tight in Florida, the campaign has insisted they do not need it to win. Despite making a last minute trip to Ohio yesterday, the campaign had not indicated it was a necessary part of their path but more of an added benefit if they could pull it off.
Two advisers tonight have also expressed optimism in Arizona, pointing to Latino support in the state – where a win could help their path to the presidency.
Despite not having early calls in these battleground states, advisers still remain hopeful about his standing.
“Let the vote be counted,” one Biden adviser said. “Our vote will come in.”
