No Republican since 1924 has ever gotten more than 40% of the Jewish vote.

Your source, jewishvirtuallibrary.com, should not necessarily be taken as very accurate. The table is from a book written by a very partisan Jewish ‘Rat (an official of the National Jewish Democratic Council, believe it or not), so their vote is likely to be somewhat overstated simply for partisan reasons. (Since when are Democrats known to use accurate numbers for anything?) Furthermore, polling techniques that may have been used to arrive at the numbers listed in the table were far from ideal, especially in the earlier years when polling techniques in general were much cruder than they are today.
