Biden’s national poll numbers — like those for impeachment — haven’t changed much in the past month

It’s hard to debate that former vice president Joe Biden finds himself in an unusual position in polling for the 2020 Democratic presidential nomination. He has held a broadly unchallenged lead in national polling and continues to be the candidate who polls best against President Trump in prospective 2020 matchups. But he also trails other Democrats in early-state polling, landing in the sort of position in those polls that generally precedes a solemn, regretful announcement from a lectern in February. CONT.
