Establishment Democrats remain concerned about preventing former President Donald Trump from completing the greatest political comeback in modern American history — even after President Joe Biden stepped aside for Vice President Kamala Harris. The concern spotlights Harris’s lack of a post-convention bump and the September 10 presidential debate, which will force Harris to speak about her radical record and how she plans to address the nation’s decline. National and swing state surveys show that Trump and Harris are statistically tied. In polling on specific issues, however, Trump holds a sizable lead, suggesting Harris’s so-called “honeymoon” stage was a sugar high.
