Something like that. A percentage in the high 30s (I'm thinking 38%) voted for Reagan in one of his elections.
There hasn't been a Republican majority from the Jewish vote since prior to FDR, but the gap is closing. And it will continue to close, since the major gains for Republicans are amongst Orthodox (lots of children, often don't vote, and generally live in Blue States) and younger Jews (often blue staters as well, and have a longer life span than that 65 year old committed Democrat). ;)
