The left and lefter. Welcome to the new two party system.
One party with 2 heads.
It truly is getting to the time when a third party must be given serious consideration. The last Romney campaign rewrote the party rules so favorably to the leftist republicans that it will require an overwhelming delegate victory by a conservative presidential candidate to rewrite them.
Better to steal the republican brand back from the liberals, but conservatives MUST coalesce around a single candidate early...even BEFORE the primary season.
