Democrats' push for impeachment really is gaining steam - but they may have already made a fatal mistake

Cody Fenwick: Easier to say the president should be impeached for committing criminal obstruction of justice, based on evidence in the Mueller report, than to say that defying congressional subpoenas is impeachable. The 1st argument is a application of the principle that no one is above the law. The 2nd rests on a much more arcane authority about the division of powers in the U.S. government~ difficult to believe this will grip the attention of a skeptical electorate. By letting the opportunity of the Mueller report pass them by, the Democratic Party may have wasted the best chance it at effectively flexing the impeachment powers. The House may still come around to the idea, but it may be too late to do much good. If they’re going to convince the public that impeachment is worth it, it will be an uphill battle, and many in the party don’t seem to have the will to take on this fight.
