There are about 52 third parties, and a lot of them are conservative.
I think the electorate of today makes a huge difference compared with the electorate of 1856, when it comes to making sudden, bold, radical changes.
I also think that it makes a difference that there were only young parties, even the oldest party, the democrat party, was only about 30 years old at the time the republicans took the Presidency.
I'd like to see the age distibution of FR.
Or even just THIS thread!!
