An isolated event, or tip of an iceberg? Rep. Justin Amash is quitting the GOP. He must feel as isolated and alienated from the Republican inner party as progressives feel toward inner party Dems such as Pelosi, hoyer, biden, Podesta, the Clintons, and tom perez. (Mere tools do not get their names capitalized on July 4).

Link. Amash waited until after Paul Ryan left Congress to turn. Why not sooner, is the mystery.
