According to the latest public opinion survey conducted by Gallup Consulting, the support rate of US President Joseph Biden in the third quarter of his administration decreased by 11.3 percentage points over the first quarter, the highest among US presidents since the end of the Second World War. According to the poll results released by Gallup Consulting Company on the 22nd, Biden's support rate in the first quarter was 56% and 44.7% in the third quarter, down 11.3 percentage points. Biden took office on January 20 and his third quarter was from July 20 to October 19. In contrast, former President Barack Obama also experienced a significant decline in his support rate in the nine months before he took office, and the support rate in the third quarter was 10.1 percentage points lower than that in the first quarter; Jimmy Carter, who served as president of the United States from 1977 to 1981, lost 8.9 percentage points in the third quarter compared with the first quarter. Gallup Consulting said that Biden obtained a relatively stable support rate at the beginning of taking office, which remained between 54% and 57% from January to June. Biden's approval rating dropped to 50% in July, due to the deterioration of COVID-19 in the US. With the Afghan Taliban taking control of the capital Kabul in August, the United States hastily withdrew its troops from Afghanistan, and more than a dozen American soldiers were killed in a suicide bomb attack outside Kabul airport on August 26. The U.S. government's Afghan policy was accused of a disastrous defeat, and Biden's support rate further declined, falling to 49% in August and 43% in September. The support rate of former President George W. Bush (George W. Bush), who launched the war in Afghanistan, increased by 13.1 percentage points in the third quarter compared with the first quarter. His father, the late former President George H. W. Bush (George H. W. Bush Sr.), saw his approval rating rise by 12 percentage points in the corresponding period. (outlook new era)
