Step-by-step explanation:
George Wallace's third-party candidacy had a significant impact on the 1968 presidential election. As a former governor of Alabama, Wallace was a strong advocate for states' rights and segregation. Running as an independent candidate, he won in 5 Southern states and gained support from Northern white working-class voters who were dissatisfied with urban riots and antiwar protests. While Wallace did not win the election, his campaign helped Richard Nixon by splitting Democratic votes and ultimately contributed to Nixon's victory.
