MOVING AHEAD ON impeaching IRS Commissioner John Koskinen. It won’t go anywhere, exactly, but it does make a point:

The last impeachment of a cabinet officer or agency head was War Secretary William Belknap in 1876. Then again, no Presidency in decades has treated Congress with the disdain that President Obama has. With rare exceptions he has also refused to dismiss officials when they fail at their most basic obligations. If the House votes to impeach Mr. Koskinen, the Senate then would need a two-thirds vote to convict in a trial, which is unlikely.

Yet the exercise will have the salutary effect of reminding executive-branch officials that they are not a government unto themselves. The U.S. Attorney has refused to honor Congress’s contempt charge against Ms. Lerner for refusing to testify, the Justice Department has closed its investigations into IRS targeting without prosecutions, and the press corps winks at abuses of power when conservatives are the targets. With an executive who refuses to honor the normal separation of powers, Congress is obliged to use its authority to hold government accountable.

I think Koskinen should be radioactive — protested at speaking events, too controversial for post-IRS employment, you know, the way lefties would treat a similar offender on the right.
