From what I can make out, Carter was a great president who unfortunately staffed his cabinet with morons....Reagan was a moron who staffed his cabinet with competent professionals.
Not that I know that much because I haven't studied it in depth, or care to for that matter, but on ther surface it seems to be the case.
Now, the argument could be made that Reagan was the better president because of his choice of staff, which is a valid point, but we are still paying for Reaganomics, and with Bushonomicsspendingeverythingonwarmongeringsomeandmyvpcangetevenricher, could leave us digging out for the foreseeable future.
