"If you are willing to elucidate a bit , I would appreciate it"
For example, Marshall picked Eisenhower for the top spot not because he was a strategic genius, but because he could take a strategic plan and implement it. He could take a strategic concept and transform it into operational orders.
DeMint was a purest, but he couldn't take his ideology and transform it into law. He didn't know how to do that, or it didn't concern him, I don't know which it was. Either way his vision just sat there in his mind where it did nothing but entertain him and others. That isn't enough. Consequently, he belongs where he's going, not in the legislative branch of government.
