Huffington Post: “The Democratic Party of James Buchanan, from 1855-1860, appeared ― on the surface ― to be ascendant in the American politics of the day. They controlled the presidency, majorities in the Congress and the majority of state legislatures and governorships. Their great rival party, the Whigs, had collapsed into internal factions after their 1856 electoral loss and the new Republican Party was nascent. They were so powerful that they controlled both the entire south and significant parts of the North ― and there was, of course, no ‘west coast blue wall’ in the 1850s.”

“Nonetheless, the supposed dominance of the Democratic Party in the late 1850s papered over and masked critical internal divisions that would destroy the party in 1860 and leave it nearly irrelevant at the presidential level for almost 70 years.”

“Basically, those critical internal divisions were between the Southern Democrats, who were unified behind slavery and ‘southern values’ and the Northern Democrats, who were much warier of slavery and were much more unified around economic concerns. Their uneasy alliance collapsed entirely in 1860, when the party actually split on the ballot between the Northern and Southern Democrats, handing Lincoln the election. The south seceded, Lincoln won the Civil War and the party didn’t recover until FDR. Indeed, the collapse of the party was so catastrophic that the only times the Democrats won the presidential election between 1856 and 1932 were typo non-contiguous terms for the idiosyncratic Grover Cleveland, and when Teddy Roosevelt split the Republican vote off Taft in 1912 and threw the election to Woodrow Wilson.”

“History repeats itself in inexact cycles, and the Republican Party of today bears remarkable similarities to the Democratic Party of the 1850s.”
