Honestly, Zionism was a political lobby in the 1930's, but it never had a strongly religious component. It was labor-socialist in a lot of senses, but Orthodox Judaism was a very different thing and only had some representation in Zionist movements. Israel itself is the outgrowth of the movement, and took on a similar character of secularized youth groups that emphasized a more nationalist identity that wasn't necessarily bound by the religious observances of Judaism, which always had variation in how the traditions are kept and practiced. Within Modern Israeli politics, some ultra-conservative groups exist that are highly traditional, but they also tend to represent a minority.

The most prominent group I can think of that is orthodox and works internationally is the Chabad and they tend to focus on bringing assimilated Jews back into the fold. Their relationship with politics is basically nonparticipatory to the point where they take no official stance on the establishment of Israel.

Basically, Judaism gets complicated fast, but there's not a lot of consensus. It seems like the response to magic would be fragmented.

I'd also say that Catholicism and Mormonism, which each have lately had their internal beliefs and subcultures on display, also would have a loud argument over magic. With Catholicism, the reaction of Jesuits would be different from more conservative elements (including American ones that think very differently from South American ones who think differently from African ones) and with Mormonism, you have different interpretations of their scripture making people decide on different priorities in a crisis. There may be splinter factions, of course, like that underage polygamy cult in Arizona that claims to be Mormon, but they have no real influence.

Islam, as we know, is pretty decentralized and has been since the fall of the Ottoman Empire. So the really big religions aren't that monolithic, even the ones we'd expect to be monolithic like the Catholics. The words of the Pope are considered guidance...I'd name a couple of politicians that exemplify that, but I don't want to start an argument.

Now when we get to something like Scientology, which is a lot more cultish, heavily monied and probably would consider magic to be their tool. There are smaller protestant groups, we might have some leverage there, especially as some megachurch pastors tend to deal with a more unified base of tens of thousands rather than millions.

Luckily, America has a bunch of megachurches and the pastors collectively have influence. I also think they'd be the least paralyzed of groups with lobbying influence in American politics. Scientology, of course...well, we can see. 

The next question regarding religious reaction is, what happens? Condemnation? Outreach/ministry to comfort the people detained in the camps as an act of mercy and redemption? Conversion therapy? Pitchfork parties? I'd imagine that with some of these groups, "Burn the witches!" becomes a thing.
