Not quite, razzle. There are quite a number of Jews who are Republicans and the number is growing. If W got at least 25% of the Jewish vote in '04 (admittedly he deserved to get a lot more), your numbers don't quite add up. Furthermore, Ronald Reagan got something close to 40% among Jews in 1980, and I doubt if too many of those came from "Liberal Democrats."
When ChessMaster said, "Jews have the same split as do Christians," I would think that he was making a qualitative, rather than quantitative, statement.
As for your statement "Christians are at least 60% Conservative Republican," the accuracy of that would depend on whether you are using a narrower or broader definition of "Christian."
"There are quite a number of Jews who are Republicans and the number is growing."
I hope you are right. As you say, it seems odd that the Conservatives are usually (except the Bucannan crowd) very pro-Isreal and get only 25% of their vote. Could the pro-America thing be a turnoff to the Jews. I hear of some American Jews saying they have more allegience to Israel than America and they have been here many generations.
