He'll never get the support of American Jewry. American Jews are too busy committing demographic suicide and parrotting their grandparents' outmoded politics to care.
One of my customers brought up a political discussion with me one day, he is Jewish and a Republican. I asked him why Jews vote for Dems in such large numbers even though it's obvious they are more supportive of Israel. He said (one mans opinion) that a large number of Jews believe in giving to the poor and helping the unfortunate in society and view conservatives as greedy.
My response was " So what can't they give to help out?" and he said his friends think the gov't should be involved to basically make people give to help the poor.
My take is this, not only Jews but many people hate the Christian right. They view Republicans as a bunch of "God Hates Fags" and people who hang outside abortion clinics calling girls murderers as they go in types.Its not true, but thats the way many see it.
