Vulnerable Democrats avoid Biden

 Axios:

Democrats in swing states and vulnerable districts in this year's pivotal midterms are distancing themselves from President Biden on social media as his poll numbers hit their lowest point.

Why it matters: The digital distance is one sign of the concern candidates feel about a person they'd normally embrace. Incumbent presidents — including one who believes he needs to come to their hometowns to sell his message — would normally be political gold for candidates from the same party.

Details: Swing-state Senate candidates like Abby Finkenauer in Iowa, Val Demings in Florida and Cheri Beasley in North Carolina, who might face tough general election races if they win their primaries, have avoided tweeting about Biden.

Many Democrats in front-line districts have also stopped mentioning the president on their campaign accounts since Sept. 1, per data compiled by Quorum and reviewed by Axios.

The September date corresponds with the Afghan debacle.  There are also dozens of Democrats in Congress who have decided not to run for reelection following the disastrous poll numbers for Biden and for Democrats in general.
