If there were ever a minor footnote in Presidential history, it may be Styles Bridges. After becoming the youngest ever Governor of NH in 1934 at the age of 36, two years later he was elected to the US Senate.
Perhaps thinking himself to be on a meteoric rise to power, in 1940 he took a shot for the Republican nomination, which ended up in the hands of Wendell Wilkie (lost to FDR in the election).
So, Styles stayed in the Senate until his death in 1961, his star fading to obscurity. He was a major supporter of Joseph McCarthy's Red Scare -- one of only 22 Senators to vote against censuring McCarthy -- and 1954's Lavender Scare, aimed at the gay community.
Possibly the seediest part of Styles Bridges career came when he and two fellow Senators blackmailed Wyoming's Democratic Senator Lester Hunt, threatening to expose Hunt's son's homosexuality of the Senator did not resign. Instead, Hunt committed suicide at his desk in his Senate office.
