WASHINGTON—Republicans looking to recapture the Senate in November have said that an apparently accelerating shift among Jewish voters from the Democrats to the GOP could significantly boost their candidates in battleground races.
Voting data going back to 1912 compiled by the American-Israeli Cooperative Enterprise show a marked shift in Jewish voting beginning with the 2016 presidential balloting as Republican Donald Trump won 26 percent, compared with the average of 23.75 percent for the four previous GOP presidential candidates.
