It was the Senate's turn Tuesday to grill the Internal Revenue Service, or more accurately, former agency officials, about its handling of the scandal involving the targeting of conservative groups seeking tax-exempt status.

Of all the controversies swirling around the Obama White House, the Internal Revenue Service scandal seems likeliest to have the longest shelf life.

While the Benghazi affair has long been in the news, it's never really taken off as an issue beyond the Republican base.

A simple idea: attack Obamacare tersely.

On the same day House Republicans scheduled their latest symbolic vote to repeal Obamacare, as part of their full-court press against the law they also took to Twitter to say, in three words, why they oppose the legislation.

Scintillating isn't how you'd describe the report issued by the Treasury inspector general's report on the Internal Revenue Service's targeting of conservative groups.

It was written, after all, by government bureaucrats for government bureaucrats. Enough said.

This was the critical moment, the brief time between his inaugural and when the nation's collective focus turns to whom his successor will be, when President Obama had to make real progress on his second-term agenda and thus forge his legacy.

Instead, the president finds his administration, the public, Congress and the news media distracted by controversies over Benghazi, the Internal Revenue Service's targeting of conservative groups and a leak investigation in which the Justice Department secretly obtained months of phone records of Associated Press journalists.
