Grover Norquist explains their capacity to tolerate Rudy McRomney:
"What brings social conservatives to the Republican party is not some list of 20 things that James Dobson would like to see. It's a much lower threshold. Social conservatives are best understood as a parents-rights movement. They don't like guys throwing prophylactics at their kids in public schools. They don't like their faith being made fun of, they want to be able to send their kids to private schools or home school. They are worried about raising their kids in their own faith and being left alone. On the abortion issue, pro-lifers need the same thing the chamber of commerce wants: serious judges. If you promise them that, credibly, you can have their support.
And each of the Republican candidates passes that threshold."
