What made Al Smith vulnerable to criticism?

Al Smith was vulnerable to criticism primarily due to his Catholic faith, which raised concerns among predominantly Protestant voters during his 1928 presidential campaign. Additionally, his urban background and association with Tammany Hall in New York City led to perceptions of him as a corrupt politician. His opposition to Prohibition also alienated some voters, further compounding the challenges he faced. These factors contributed to a broader skepticism about his suitability for the presidency.
