I doubt it. MLK Jr. at one point was called a communist because he advocated the rights of the working poor as well as civil rights, and some people feared President Kennedy polices as being "too progresive."

Yes, and by modern standards, either would be an *arch* conservative. Affirmative action would be utterly abhorent to MLK, it is "judging people by the color of their skin, rather than the content of their character". JFK would be uttery incensed by the extent of the US welfare system, he advocated the rights of the *working* poor, not the non-working poor. He would consider the current deficit levels utterly ludicrous, the power grabs by obama utterly beyond the pale (he was blasted for asking US steel not to raise prices).

Now, if you took either person and transported them to the current day as babies and raised them under similar equivalent conditions, then *maybe* you'd get there, but straight transportation of either one would be very very likely to dissapoint you.

This is going to be an artifact of virtually any historical figure, progressivism has been making inroads into new extents of federal authority for *generations*, virtually no historical US figure would be considered "left wing" by current standards.
