Americans can learn from the Jewish American community. Jews represent about 7 percent of the US population. Since half of the eligible voters do not register and typically half of the register voters do vote. That means out of 100 Americans, 50 register to vote and about 25 actually go out and vote. In a close election the winner needs about 13 of the 25 active voters. If half the Jews in the US register to vote, and 8 of the 10 register voters go out and vote, that means they represent 2.5 voters of the 25 voters. If you can get 90 percent of the 2.5 voters to vote for you, they represent 2.3 voters of the 13 needed to win a close election or the Jews would represent about 15 percent of your winning coalition. The secret to Jewish American political power in US election is massive voter participation while the rest of Americans sit dumb, fat, and ignorant. Observe what Arab Americans are starting to do in their enclaves, they are studying and replicating the Jewish model. Their numbers are growing faster than Jewish numbers. Be interesting to see how these two groups attempt to influence US policy in Middle East and towards Islam.
All your points may be correct, but they fail to answer the basic question-—why do Jewish voters so heavily support left-wing causes, which, at bottom, are antithetical to their own interest. You can bet that Obama is NOT going to be as strong a supporter of Israel as McCain.
