Democratic voter registration raises red flags for Harris

Democrats’ voter registration advantage has dropped in three key battleground states — Pennsylvania, North Carolina and Nevada — raising a red flag for Vice President Harris as experts cite a lack of enthusiasm for the Biden administration brand and the Democratic Party, generally, as problems.

In Arizona, another key battleground state, Republicans have seen their voter registration advantage increase substantially, which could make it tougher for Harris to carry a state that President Biden narrowly won in 2020.
