You don't need anonymous reports from campaign sources to know the Democrats are terrified of losing the "Blue Wall" states. Harris is losing steam so quickly in each of those three states that other Democratic candidates are putting up ads saying they support Trump's policies. It seems Harris is not only losing the country but her party, too.
AllRecent the recent polls show is that this race is close, which puts Harris' grassroots campaign in a strong position. As Donald Trump continues alienating voters with his anti-democracy language, and Harris continues to meet with swing state voters, the Democratic nominee is on a path toward winning women, minorities, and the Electoral College.
There's a 52% chance that Trump will be elected US president in 2024, according to the Metaculus prediction community.
