With Democrats seizing the House and Republicans keeping the Senate, bills beyond the proverbial post-office-naming will be hard-pressed to make it out of both chambers in the next Congress. The threat President Trump faces from Democrats, then, isn’t legislative obstruction, but the ready-aim-fire of the opposition’s “subpoena cannon.”

That’s the term one senior Democratic source used last month in describing to Axios the opposition’s main anti-Trump weapon. Not all of the investigatory weapon’s payload will be fired at once, but the appetite for “resistance” is strong and will tie up significant White House and agency resources. (Full disclosure: My wife is a lawyer in the House general counsel’s office, but hasn’t participated in any discussions regarding the Democrats’ plans.)
