Eric Greitans is Jewish, and he got elected in Evangelical Missouri of all places.
Lower-profile there's also David Kustoff, the Republican Congressman from West Tennessee.
I wonder if the largest contiguous area to be represented by Jews in Congress is actually in Tennessee, lol (Steve Cohen, who represents neighboring Memphis, is also Jewish.)
Yeah, I wonder this too, and it's pretty impressive considering the former (TN08) is the Bible Belt and the latter (TN09) is a very black district and the representative is white (a white Jew). but pretty possibly no, because while TN08 is pretty large, TN09 is so tiny that TN08+TN09 in area is about the size of one large district...so find the largest district in the country to be represented by a Jew and it probably beats TN08+TN09.
EDIT: So I did a check of all Jews currently in Congress and their CD's, and I'm wrong - most predictably come from small, urban/suburban areas. So I can almost guarantee that TN08+TN09 is the largest block of contiguous land represented by a Jew in congress; in fact, I'm pretty sure TN08 alone is the largest district by area in the entire country represented by a Jew (I could be wrong but it looks like it after I eyeballed the other districts).
