18th and 19th Century Presidential Eras

[Mehmentum]

Welcome to the forum!  I would say that the Republican era should start with either the 1856 election or the 1860 election.  (the first time a Republican ran on the national ticket and the first Republican president respectively.)  Meanwhile, the New Deal Era hould definitely end with Carter.  The next era would start with Reagan and continue on to... well its to soon to say where it will end.  It may have ended with 2008, but only time will tell.

I'd think the Reagan era would stretch all the way to George W Bush.  As it stands, 3 presidential elections seem to be pretty short for an 'era'.
