Betty Boop sings a push for votes in Betty Boop For President (1932). And she does impersonations, too, morphing her appearance. Oddly, she doesn’t turn into F.D.R., who won the election that year.
The stiff collar indicates Betty is doing an impression of President Herbert Hoover.
She’s now Al Smith, who lost the Democratic nomination in 1932 to Roosevelt (after losing the presidential vote four years earlier). Comedians made fun of the fact that Smith insisted on calling a radio a “raddio.” Betty does that, too.
Gag’s over. She pulls down the brim of her hat and becomes Betty again.
Betty wins the White House at the end of the cartoon, thanks no doubt to animal rights activists (cars are stopped to allow cats to cross a city intersection) and supporters of heterosexual conversion therapy (a hard-boiled inmate is effeminised).
Seymour Kneitel and Doc Crandall get the animation credits. Mae Questel is Betty. I don’t know if New York-based radio mimic Johnny Woods supplied the voices of Hoover and Smith; I’d have to listen more carefully to see if it sounds like him.
