Frum wants one:
If moderates are to flourish, they need an infrastructure to support them. The Democrats worked hard in the 1980s and '90s to showcase their centrist governors. They invented superdelegates to balance the left-wing activists who had saddled them with unelectable presidential candidates. They altered their primary schedule to enhance the clout of must-win states in the West and border South.
Republicans can learn from these examples. But first they have to say it loud and say it proud: The time has come to restore the center to the center-right coalition. Maybe it's even time to start a new convention so the centrists can meet face to face at least once a year, just as their conservative colleagues do. CenPAC, anyone?
