As this series has tried to show, there was an increasing divergence between the vision of the Republican party as seen by the old-style conservatives and that seen by the new alliance of Christianists and neoconservatives. Looking back, it seems inevitable that the tension would become too great and the party finally snap.
It was Sarah Palin that was the last straw. We saw how towards the end of the campaign, many leading old-style conservative Republicans, their party’s intellectual backbone for so many years, abandon their party and support Obama, citing McCain’s selection of Sarah Palin as the reason for their defection. I suspect that that was not the sole reason but that their disillusionment had been brewing for a long time and this was the defining event that pushed them over the edge.
