Key quotes:

President Joe Biden and his campaign are insisting he will stay in the 2024 race, despite a rough debate last week in which he looked feeble and struggled to complete his thoughts several times. With Democrats increasingly unsure that Biden should remain the party’s nominee, the conservative Heritage Foundation is pledging to try to block the Democratic Party from replacing Biden on the ticket in key swing states.

In a June 21 memo, the Heritage Foundation astutely predicted that Democrats might wish to force out Biden “if he freezes at [the] debate.” Noting that “the mechanisms for replacing him on ballots vary by state,” the memo says: “There is the potential for pre-election litigation in some states that would make the process difficult and perhaps unsuccessful."
