The Democrats will BEG the Republicans to do it after 2014 so they can have their scapegoat.
That’s a good point. The Republicans wait until after the mid-terms and the new congress draws up articles of impeachment early on. Then they’ll have a stronger majority (and hopefully a louder voice) and the charges will have plenty of time to be proven valid prior to the 2016 election, so it’s a lot less likely to backfire (through a false media narrative) on those voting for it.
