For those of us whose respect and admiration for Ron and Carol predates his 2007 campaign for President, pinpointing exactly "what" or "when" is, for me anyway, very difficult.
I think I've mentioned this before here on the DP. For some of us (longtime Lp'ers and Cp'ers) he's been a regular fixture in our circle and at our annual events for so long that he's just Ron.
When I see Ron and Carol I don't see what the newcomers and youngsters see (though I wish I did), it's more like that Aunt and Uncle that you never see but at family reunions every couple of years. Ron and Carol are like family to Libertarians and Constitutionalists.
