The more I think about it, the more I notice certain parallels between the 1928 and 2016 elections. Bear with me here for a bit...
* BOTH YEARS, the Democratic Party nominated experienced New York politicos who rejected radical reform in lieu of incrementalism (Al Smith/Hillary Clinton).
* Both Al Smith and Hillary Clinton won unprecedented support and money from usually Republican Wall Street. Smith and Clinton both favored the corporate '"establishment" wing of the Democratic Party and lost support from the "populist" and "progressive" elements (Smith failed to thrill Bryan voters; Hillary failed to thrill Bernie voters)
* Both Al Smith and Hillary Clinton failed to stake out bold policy positions on the soaring inequalities in their eras. Smith refused to endorse a progressive farm policy; Clinton refused to endorse singe-payer healthcare. Their essential conservatism cost them both dearly among a certain kind of Democrat.
* Both Al Smith and Hillary Clinton ran as unapologetic champions of The City in an era of cultural upheaval. Smith and Clinton both embraced cultural liberalism and won record support in the nation's big metropolitan areas for it, especially among immigrants and yuppies. They both got massacred in rural areas and small towns across the nation for the same reason.
* Both Al Smith and Hillary Clinton brought in new voters from odd places to their party- Smith got some usually Republican Midwestern farmers, Clinton got some usually Republican Midwestern professionals. Both lost more than they gained since so many Democrats jumped ship (white southerners and Bryan-voting progressives from Smith, working-class whites and progressives from Clinton).
* BOTH YEARS, the Republican Party nominated a wealthy businessman without experience in the military or elected office (Herbert Hoover/Donald Trump).
* Hoover and Trump both benefited from racist/nativist themes. Both men were strongly supported by groups embracing those themes, whether the Ku Klux Klan in the 1920s or the "alt-right" in the 2010s. Both tacitly condoned such activity.
* Both elections resulted in total Republican control of the federal government.
Does that mean Trump is the next Hoover? Hard to say. Anyone see other parallels or is this stretching?
There is also a theme of 'normalcy" barrowed from the 1920 election, where, like Trump, Harding ran against internationalism and progressivism.
Both Hoover and Trump were considered "not really conservative" and at various times had as a policy of replacing regulations and taxation with tariffs. They both have reputations as Prohibitionists, and both come from a point in time where there has been of time of economic inequality, speculation, and instability following a preceding prosperous era.
