Reconstruction America would have elected Ed Gein, had he been the Republican nominee.
No "trends" or "patterns" can be inferred from the Reconstruction years. Unique point in history.
right after the Civil War you're probably right, but Hayes had to steal the election.
No doubt he stole that election. Both parties were very very dirty in the 19th century. Read about how Poe died. He died from alcohol poisoning. Democrats in Baltimore got him drunk and forced him to vote 5-6 times in a mayoral election. Plus in 1876 I think some southern states EVs weren't even counted or they were thrown out.
