Democrats are trying to ignore this, but what @WVUALLEN has posted here is clearly showing up in polls among Blacks (and Hispanics) who used to be nearly lock step in support of Democrats.
excerpt:
Among Black Americans expressing a party preference, the Democratic lead over Republicans has dropped by almost 20% in only three years, according to the Gallup survey. The Democratic lead among Hispanic adults and adults aged 18 to 29, meanwhile, also slid by almost the same degree, leaving the party with only a modest advantage. “These shifts in the party affiliation of key subgroups provide the demographic backstory for how Democrats went from enjoying significant leads over Republicans between 2012 and 2021, to slight deficits in 2022 and 2023,” the research company said in a statement accompanying the survey. “The 27% of US adults identifying as Democrats and the 43% identifying as or leaning Democratic are both new lows in Gallup’s trend.”
