Will a Democratic Senator call on Biden to drop out?

This market will resolve to "Yes" if any Democratic senator publicly states that Joe Biden should drop out of the 2024 presidential race before 12:00 AM ET on the first day of the Democratic National Convention, currently scheduled for August 19, 2024. Otherwise, this market will resolve to "No." Statements that the Democratic party should nominate another candidate other than Joe Biden will also qualify for a “Yes” resolution. Statements that are hedged or express ambiguity, such as “We need to consider our options for the nominee” will NOT qualify for a “Yes” resolution. If the DNC does not begin by August 31, and any Democratic senator has not called for Biden to leave the ticket, this market will resolve to "No." A senator will be considered to be a member of the party they caucus with. The primary resolution source for this market will be official statements by Democratic senators or their official representative(s); however, a consensus of credible reporting may also be used.
