Candidates Vie for Jewish Support by Embracing Israeli Government Policies
Allan C. Brownfeld, Editor; Special Interest Report; May - June 2004
At least that article, despite the fact it came from a leftist Jewish web site, suggested that Republicans were actively courting "Jewish leaders" and making gains improving their acceptability in the Jewish community.
I suppose the major point of your link is that Republicans even in 2004 had valid reasons to claim they were the more pro-Israel of the two major parties. Yes, that's very true, but Republicans have been saying this since at least 1985, when the Republican Jewish Coalition (formerly the National Jewish Coalition) was established. This national organization of Jewish Republicans has grown impressively in membership since then.
Remember that Reagan in 1980 got a larger percentage of the Jewish vote than any GOP presidential candidate since Warren Harding.
