Ukraine is a relatively strong issue for Biden
As Biden touts his support for Ukraine in its war against Russia -- calling it out as one of his defining successes of the past year -- he is speaking from a position of relative strength: Americans generally feel better about Biden's Ukraine policies than about his domestic ones. For example, a recent ABC News/Washington Post poll found that his approval rating on the Russia-Ukraine conflict (38%) was higher than on the economy (37%) or the immigration situation on the U.S.-Mexico border (28%).
In addition, according to Gallup polling, a plurality of Americans (39%) think the U.S. is doing the right amount to help Ukraine, while 30% think the U.S. is not doing enough and only 28% think it is doing too much. However, as my colleague Cooper Burton wrote last month, support for aiding Ukraine has cooled a bit since the war started in February 2022, thanks in large part to decreased enthusiasm among Republicans.
