President Joe Biden’s job approval rating among Democrats has tumbled 11 percentage points in the past month to 75%, the worst reading of his presidency from his own party. This drop has pushed his overall approval rating down four points to 37%, matching his personal low.

At the same time, Biden’s approval among independents has declined four points, to 35%, while Republicans’ rating remains unchanged, at just 5%.

Biden’s immediate and decisive show of support for Israel following the Oct. 7 attacks by Hamas appears to have turned off some in his own party, resulting in Democrats’ worst assessment of the president since he took office. Biden’s overall approval rating likewise matches his personal low. The Israeli-Palestinian conflict comes at a time when Americans remain pessimistic about the economy, the Biden administration is struggling to deal with increasing numbers of migrants attempting to enter the country, and debate continues about how much aid to provide to Ukraine in its war with Russia.

As events in the Middle East continue to unfold and the humanitarian crisis in Gaza worsens, Biden’s guidance on Israel could affect not only the outcome of the war but also how he is viewed at home.
