Andrew McCarthy of National Review Online identifies a key problem with congressional Democrats’ impeachment case against President Trump.

Everything that is happening owes to the fact that we do not have an offense sufficiently grave for invocation of the Constitution’s nuclear option. If we had one, the machinations and the posturing would be unnecessary — even ridiculous.

Why are we talking about how Chairman Schiff, Speaker Pelosi, and House Democrats rushed through the impeachment inquiry without making a real effort to interview key witnesses?

Why was the Democrats’ impeachment gambit driven by the election calendar rather than the nature of the president’s offense? Why were the timing of hearings and the unreasonable limits imposed on Republicans’ ability to call witnesses dictated by the frantic rush to get done before Christmas recess — to the point that Democrats cynically vacated a subpoena they’d served on a relevant administration witness, fearing a few weeks of court battles that they might lose?

Why did Democrats grope from week to week in a struggle over what to call the misconduct they accused the president of committing – campaign finance, extortion, quid pro quo, bribery? How did they end up with an amorphous “abuse of power” case? How did they conclude that an administration that goes to court rather than instantly surrendering potentially privileged information commits obstruction? …

… None of this would have happened if there had been a truly impeachable offense.

Adam Schiff is a smart guy. He did not idly dream up a “make up dirt” parody. He framed it because he knows that’s the kind of misconduct you would need to prove to warrant impeachment and removal of a president. In fact, Schiff could never prove that, but he figured parody is good enough for 2020 campaign purposes — and that’s what this exercise is all about.
