I've Been Wondering

When conservatives say that liberals always "blame America first," or that liberals are in the "blame America first crowd," are they trying to draw parallels to the America First Committee that opposed entry into World War Two?

Nobody seems to want to admit it. And if it's not, it's pretty awkward phrasing. Maybe it's just one of those things where a slogan becomes popular despite its stupidity because hey, everyone else is using it.
