I prefer a natural born citizen as one who has always loved and admired America, one who is America first, and wants to stop importing unskilled, unvetted and religious bigots as immigrants. Romney satisfies your definitions of NBC, but I still do not prefer him over someone like Mark Steyn.
Romney may be eligible, but he had his chance and took a dive.
Steyn is someone I like a lot but is not eligible.
The natural born citizen clause served us well until we ignored it.
Barry Soetoro/Barack Hussein Obama is proof enough of their wisdom.
