Rachel Maddow talks to Lincoln Chafee about the Club for Growth and other conservative groups pouring money into the Republican primary process and demanding "purity" from their candidates on right wing conservative issues, and then that candidate going on to lose a general election. Rachel asks whether that strategy is going to mean the end of the Republican party or a possible formation of a third party. Chafee does not see the party changing and feels they're not going to remain a viable national party.
