What you wrote was 100% correct 8 years ago and was a view typically shared by the older Jewish population. I know a few Jewish people and Obama rubbed them the wrong way.
Obama has rubbed a lot of people the wrong way. But Jews haven't politically shifted in a way that has made them go from progressive to conservative.
Also, personal experience is also a horrible tool to use to try and prove a political point. People's personal experiences often work to confirm their own personal biases because people tend to associate with people they lean politically with and a lot of times their personal experiences go against what is actually happening. If I went by personal experience, Barack Obama would have lost New York state by massive margin.
The younger Jews post college do not see it the same way their parents did. I'm not saying the Jews will abandon the democratic party. I am saying a greater percentage of them will be voting Republican.
The shifts we've seen of the Jewish demographic from Democratic to Republican have been small and insignificant. It's not like the major shifts we've been seeing like Hispanics becoming more Democratic and whites becoming more Republican.
IF the Republicans offer a path to power for Jews in the state of New York of Florida, you could see a significant shift.
1. Republicans already control Florida.
2. The path for Republicans in New York is not with the Jewish vote, but the suburban white vote. Monroe County, Erie County, Westchester County, and Onondaga County in Upstate New York along with Nassau County and Suffolk County in Long Island. Winning the suburbs in those counties is enough to counter Rochester, Buffalo, Yonkers, and Syracuse and winning the Long Island suburbs along with GOP advantages in rural Upstate New York would be enough to counter New York City. But of course the GOP these days just loves to alienate the suburban voters.
3. Offering demographics token positions of power don't mean anything. It's all about ideology. The Jewish demographic is overall a progressive demographic. It's almost the same problem (though nowhere near as extreme) the GOP has with the black demographic, a demographic that is borderline democratic socialist is not going to hit it on with a conservative party.
4. Family ties to a political party take generations to tear down dude. Only now after decades worth of developing under Nixon has the GOP destroyed the Democratic Party in the South. Obama sped things up a bit, but it still took a while for the GOP to win the South beyond just Presidential elections. To think that Jews will just suddenly leave the Democratic Party just because of Barack Obama (a President that they still mostly agree with ideologically), is absurd.
