The strength of the U.S. economy resulted in Hoover's Republican Party victory in the election, helping them to scoop up 32 House seats, almost all from the opposition Democratic Party, thus increasing their majority. The big business-supported wing of the Republican Party continued to cement control. Republican gains proved even larger than anticipated during this election cycle, as an internal party feud over the Prohibition issue weakened Democratic standing. Losses of several rural, Protestant Democratic seats can be somewhat linked to anti-Catholic sentiments directed toward the party's presidential candidate, Al Smith.
However, this would be the last time for 68 years that a Republican House was re-elected. This is the last time that Republicans won the House popular vote by double-digits.
