The GOP – BackStory with the American History Guys: http://backstoryradio.org/shows/the-gop/
Lincoln and the Radical Republicans really defined the party, despite the wishes of “Conservative” types, at the outset. It really is too bad that faded, and Conservatives feed off of Lincoln’s example unreservedly.
Our democratic republic’s systems need to breakdown the “two-party” dominance. I’d go so far as to say we need a three-party system: Republican Party, Democratic Party, Conservative Party.
It would/could allow for inflections. Greens, liberals, conservationists, conservatives, hawks and doves, permeating all three to various degrees.
