2 things have always concerned me.
First, in Presidential Elections the electorate votes their generation. Since 1860, the president elect has been younger than his predecessor, with 2 exceptions. 1, Harrison defeated Cleveland. He lost the popular vote, but won the Electoral College. 2, Reagan defeated Carter with 18% interest rates and "America Held Hostage".
Second, 1936. FDR had a worse economy but the Depression started after 12 years of Republican rule. Some economists point out that the Stock Market bottomed out in July 1932 and the Depression was over by March 1933. However, full employment was slow to return and FDR's shifting policies made business cautious about hiring, much like today.
