Things were looking good for Joe Biden for a while. A big economic relief package passed in March, coupled with a stellar vaccine rollout in the spring and summer, helped boost his approval ratings, which almost reached 55 percent in late May. But since then, a spike in inflation as the economy tries to rebound has hurt Biden's poll numbers, which took a further hit amid the chaotic and widely-criticized withdrawal from Afghanistan last month. Excluding Donald Trump, Biden currently has an approval rating lower than his five predecessors during this same period in their presidencies. We take a look at Biden's approval and disapproval ratings against the backdrop of relevant milestones.
