Evidence of Misstep by Putin

It is now clear that instead of restoring public confidence in the political system, the announcement that Mr. Putin and President Dmitri A. Medvedev would switch jobs annoyed many Russians. Mr. Putin’s approval rating briefly dipped to 61 percent this month, high by international standards but lower than at any point in a decade.

Meanwhile, the governing party, United Russia, has had to scale back its expectations for next Sunday’s parliamentary elections, when it is likely to lose the two-thirds majority it has held since 2007.

The announcement, in other words, seems to have had an unintended negative effect, a jarring outcome for a government that has proved itself adept at measuring and manipulating public opinion.
