I think three simple actions would take him down a big notch. First, in early January....run the vote in the House and Senate to have a written State of the Union address only....no verbal delivery. Second, have the Senate request a special prosecutor over the IRS stuff...if denied....run Senate hearings for all of 2015 over the topic. Third, deny his picks for Attorney General, and force Holder to sit there until summer of next year.
The only problem is the GOP doesn’t have balls to do even one of those things.
