Perhaps I'm connected with an unusual group of practicing Jews, but they all basically tell me some variant of, "We know his tweets are dumb, but his daughter is Jewish, and it's clear he has Israel's back, so we're all in."
As a member of one of the largest congregations in the US and a 'knower-of-many-Jews", if that is common then I think you do know an unusual group. Most I know are vehemently opposed to Trump. Those who are in favor primarily seem to be those who solely focus on the economic side of politics and ignore social issues, with a smattering of fringe deep state conspiracy theory toting fox news zombies.
Most Jewish people like myself are liberal and vote for the Democrats*, even if financially we become worse off because of increased taxation.
Here's Paul Krugman's take on why that is from his column, "Donald Trump Is Bad for the Jews"
https://nyti.ms/2sdp6mI"Most of us, I think, know that whenever bigotry runs free, we’re likely to be among its victims.
The Trump administration is, beyond any reasonable doubt, an anti-democratic, white nationalist regime. And while it is not (yet) explicitly anti-Semitic, many of its allies are: “Jews will not replace us” chanted the “very fine people” carrying torches in Charlottesville, Va. You have to be willfully ignorant of the past not to know where all this leads. Indeed, it’s happening already: anti-Semitic incidents have soared (and my hate mail has gotten … interesting).
Jews aren’t the only people who have figured this out. Many Asian-American voters used to support Republicans, but the group is now overwhelmingly Democratic. Indian-Americans, in particular, are like American Jews: a high-income, high-education group that votes Democratic by large margins, presumably because many of its members also realize where white nationalism will take us.
In all of this, Republicans — not just Trump, but his whole party — are reaping what they sowed. Their strategy for decades has been to win votes from working-class whites, despite an anti-worker agenda, by appealing to racial resentment. Trump has just made that racial appeal cruder and louder. And one has to admit that this strategy has been quite successful."
