In 1964, after the Goldwater defeat, there was talk of a Third Party. In 1974, after the Nixon fiasco, there was talk of a Third Party.
Talking about Third Parties, from a GOP perspective, has always been with us.
The Democrats do not talk about it--but the socialist wing of the Democrat Party just does it. The Socialists in the Democrat Party created the MoveOn.org effort, financed ACORN, gave Obama jobs for many years, now the socialists agenda is White House policy.
Socialists did not talk about Third Parties, they just create the finances, policies and candidates to promote their agenda within the Democrat Party.
