Earlier this week a poster started a thread that avocated that all Jewish people vote Republican. The writer of the article that proposed the idea, which the thread poster apparently supported, gave reasons why he felt the way that he did.
I instinctively realized that the proposal was wrong but did not have any facts at my disposal and did not have time to gather any. I thought about the issue and gathered some data that, I think expresses why Jews, instead of voting enmass Republican, should continue to split their vote between the two major parties.
Currently about 30% of Jewish voters vote Republican. By inference, 70% either vote Democratic or for some other party, the reasonable assumption is that nearly 100% of the non-Republican votes are for Democrats. The poster of the thread that I mentioned earlier proposed that the Jewish vote for Republicans go to 100%. I think that in the best case, it should not go to more than 50%-60%. The 50%-60% region is a "safe" region where Jews cannot be identified as big supporters of either party, this allows proper exercise of influence within each party without the burden of being identified as a special interest group.
There is a currently hidden and compelling reason why US Jewish people should maintain influence in both major political parties. This reason is the political relationship between Jewish interests and events in the Middle East. Events in the Middle East are of interest to people in the US that are of Islamic religion. In 1965, the Jewish percentage of the population was ~3%. 1965 was the year that the United States reopened immigration to the US for skilled Islamic people from the Middle East, that immigration had been closed since 1924. The islamic population has grown since then, with the most rapid growth taking place in the last 24 years. The growth in the last 24 years has been concentrated among the more radical segments of Islam, as opposed the the growth during the preceeding years, which was from the more educated, skilled and moderate members of that faith. Currently people that identify themselves as Jewish make up 2% or the US population. People that identify themselves as Islamic make up 1.3% of the US population. The Jewish birthrate is stagnant or declining (no net replacement growth in the population of that group), while the Islamic growth rate is among the highest of any US population group. It is completely plausible that within 10 years or less, the Islamic population will overtake the Jewish population here in the United States and will ultimately exceed the Jewish population in a manor similar to what has happened between Blacks and Hispanics (the Black population has fallen from 12.3% in 1965 to 12.1% in 2001, while the non-white Hispanic population grew past 12.5% in 2001. Hispanics have a far higher birthrate than Blacks and a somewhat lower deathrate, so the expectation is that Hispanics will grow to be a much larger group than Blacks).
So one would ask, how does the gibberish about population growth have anything to do with how Jews should vote? It has everything to do with how Jews should vote. If Jews go 100% Republican, then it is logical to expect that US citizens that identify themselves as Islamic would ultimately vote 100% Democratic. Since the Islamic population will more than likely be larger in 10 years or less, they would have more power via their identification with a single party. Ultimately a situation will exists that is similar to France today, where the Islamic population overwhelmingly out numbers the Jewish population, with the two groups taking vastly different political voting paths. Jews in France are having a difficult time with the loss of influence, even though French Jews have significant economic power (in Media, Industry, Medicine, the Arts, ect).
It is better for both US Jewish people and US Islamic people to split their votes between the two major parties. It is especially important for Jews to do so, given the expectation that they will be outnumbered by Islamic voters in the near future. By splitting their votes between the two parties, Jews can use the inter-party mechanisms to continue to have their voice heard on a consistent basis.
