Seems ordinary Canadian folk have no idea what it means. From the sample here in this forum, I'd suggest ordinary US folk have no idea either (although the sample here in this forum is very anecdotal, way too small). Seems to me like there's lots of "blindly following based on feelings not facts or logic" for use of the term.
Note: No I didn't have any awareness of this poll being conducted ( I laughed about the timing of its release when I saw it this morning) and no I am not associated in any way to it, the company that did it, the CBC, any of the Candian political parties, etc... I also have no awareness of how the polling company may lean one way or the other or if they have credibility for being impartial (but they seem to imply they tried to stay neutral).
