Republican politicians and activists can barely contain their glee at the simultaneous eruption of three major controversies about the Obama administration.

Conservatives are at a low boil over the administration's dissembling about its actions after the attacks on the U.S. diplomatic mission in Benghazi, Libya. The public is concerned about the targeting of conservative groups by the Internal Revenue Service. And even liberals are outraged by the administration's heavy-handed investigations of leaks to the news media.

Finally, many Republicans think, the tide is turning against the Democrats. Republican strategists — and the few conservatives on Capitol Hill who were in Washington during the Clinton years — are less excited. They fear that the party is about to repeat the mistakes it made in 1998.
