Divide and Conquer
We have ALREADY been divided and conquered as Republicans, so conquered that people are prepared to vote FOR the very things they oppose.
In 2012, those who voted for Romney voted for a functional Democrat and also voted for turning the Republican party even harder left than it was; those who re-elected guys like McConnel, Boehner, and Cochran voted to keep the Republican party functionally Democrat.
Of course, when they voted for those leftist Republican leaders, they denied it, saying they were actually voting against the opposing Democrat.
