the real test is if they try to impose draconian measures on the sovereignty of a state. Blue states with Democratic Governors will NOT accept that, and that may result in a Constitutional Crisis, or worse.

I'm giving you a thoughtful and detailed reply.
First part:
Yes tcf and a his followers do pose a threat to the Jewish community, and to many other groups.
The extent and scope is unfathomable. Jews have faced antisemitism, discrimination, segregation, death, expulsion many times throughout our history. Your question gives me an opportunity to share my darkest fears and concerns. My mind has mulled this over for days.
I wouldn't be surprised if we were asked to sign a loyalty oath, not just Jews but everyone.
Those that don't or won't sign will be fair targets for whoever's up for hunting "traitors", which is what anyone who doesn't pledge loyalty will be.
I've seen data reporting that 79% of Jews voted for Harris, only 21% for tRump. I've also seen one report of 66% Harris 31% tRump. Either way the majority of us did not support him. That makes us a target! The idea of pledging loyalty is common in fascist regimes. In Nazi Germany those who didn't join the party were brutalized and ostracized (not that Jews were allowed to join). Then things get worse from there....mass deportations of Jews and other undesirable types could certainly happen, might be the best we could hope for. I don't think we'll be the first group targeted, but we will be a target. He could arrange something with his buddy Bibi to return us to Israel.

Second question: most of the states with the largest Jewish populations are Democratic, NY and California
the top 2, combined have about 3 million. They would be the safest in my opinion. The states of Florida, Texas, Ohio, and now Pennsylvania with a Dem Jewish governor voted red, and have large Jewish populations. This will now become a Christian nation. Isn't there some Christian prophecy about the Jews returning to the holy land before Armageddon and the return of their Lord and Savior? Non democratic governors or states may not do enough to protect Jews from hate crimes and hate groups. They can easily justify that we deserve it since most of us didn't vote for their leader! Democratic states and governors will offer more protection than others.
That's all I've got to say. I live in NC and we just elected a Jewish governor, so I feel a bit safer but still think about having to move and where I might go, in the US and also abroad.

Since I looked it up, here's the top 11 states, all have over 150,000 Jews.

New York
1,785,727
California
1,234,540
Florida
672,465
New Jersey
626,220
Pennsylvania
434,165
Illinois
325,160
Massachusetts
301,880
Maryland
240,100
Texas
175,655
Ohio
151,640
Virginia
150,620

. . . but in this election, there was a strong movement in much of the orthodox and ultra-orthodox towards Trump that was and is obvious amongst Jewish social media influencers who gained fairly substantial followings post Oct 7. They really hated Kamala and saw her as a threat against Israel. This was particularly so after she agreed with a heckler that Israel had to stop the "Genocide" against Palestinians. All the Israel-hate expressed by many liberals did not help this, nor did the fact that the democratic party is home to "the squad."

While I hope I am wrong, I do not see a kumbaya moment coming between Israel and some of its neighbors, so the hatred will continue. I also do not see Israel backing down in the interest of a premature cease-fire, i.e., one that does not include the return of all of the hostages and recognition of Israel's right to exist, explicitly stated from Iran on down to its proxies.

The pogrom in Amsterdam, as small as it was compared to events in our history, is another turning point. Hopefully, that energy will not manifest here more than it already is, and it is. That is a hope, not a prediction, for I do think it will get worse here, and it will come out of the radical left more than the trumpians. At this point, I carry more concern about a Kefiyeh-wearing college students and Islamist infiltrators than I do about their opposites on the far-right.

None of this means that I in any way support the far-right or Trumpism—the opposite, of course. I am a life-long Democrat.

But I do believe that this is something that Democrats ignore at our peril.

On edit: One more odd piece is that the strongest pro-Israel support in this country seems to be coming from the evangelicals. I know that their reasoning sucks, but that movement is still happening. There are many facebook groups that are very pro-Israel that are made up of Christians. Maybe their reasoning is the ridiculous second coming when all Jews live in Israel, or maybe they are recognizing that without us, their religion would not exist--I don't really know. But it's also a piece in this very large puzzle.

if he loses it's the fault of the Jews he put MAGA crosshairs on every Jew in America.
