Would Huey long have challenged Roosevelt for the presidency if he had not been assassinated?

It is widely believed that Huey Long would have posed a significant challenge to Franklin D. Roosevelt for the presidency had he not been assassinated in 1935. Long was a charismatic and populist figure with a substantial following and a platform that appealed to many disenchanted with the New Deal. His ambitious "Share Our Wealth" program aimed to redistribute wealth and provide economic security, which could have positioned him as a formidable contender. However, the political landscape and dynamics of the era would have ultimately influenced the viability of his candidacy.
