the jewish vote is very important in some places, but - for instance - it didn't amount to much in the two congressional districts in the south where black candidates were defeated by less-critical-of-israel blacks, whose campaigns were financially helped by the lobby...
it isn't votes alone, but the money with which to purchase them that loom larger...money is why american blacks , though greater in numbers than american jews, have much less power in congress... and most other institutions.
