"Show me just what Mohammed brought that was new, and there you will find things only evil and inhuman, such as his command to spread by the sword the faith he preached." - Manuel II Palelologus
This reminds me of 1992. I talked myself hoarse trying to tell people that BillyJeff wasn't serious about his three signature issues in that campaign: a middle class tax cuts, "ending welfare as we know it," and balancing the budget. All were Republican themes, and all served to peel away soft Republican voters who were frustrated with Mr. Read My Lips.
BillyJeff was elected. The middle class tax cut turned into a massive tax increase. "Ending welfare as we know it" turned into an expansion of the Earned Income Tax Credit (which the Clintonites also scored as a tax cut). And Clinton dropped entirely any attempt to balance the budget; he never proposed a balanced budget nor a glide path towards one. Welfare reform and a balanced budget were of course driven by Gingrich and Armey in '95-96, with Clinton as the main opponent, and after they were done Clinton took credit, but that's another story.
What Clinton demonstrated is that Democrat voters are now essentially tribal. Issues don't matter as long as a couple of big identity politics taboos are observed. The Democrats are motivated two things: the promise of payoffs and, probably even more, resentment of a scapegoated opponent. Obama can reverse himself as many times as he wants; most dems won't care.
