Reply #9: I see two possible intentions.

[Behind the Aegis]

1) this is a "subliminal" or "dog whistle" call to right-wing fundies, playing to religious anti-Semitism, in some fashion.

2) this is a way to "relate" to Jewish voters, akin to saying "conservatives are the new Jews."

It could possibly be a combination of the two, the big problem is the second possibility is more likely to upset Jewish voters than sway them in any way to look to conservatives. Of course, it also could simply be what I see in a variety of cases, co-opting another's experiences to suit one's needs, in this case, the hate enacted against Jews in the past and today.
