The fun part about GEOTUS saying "we should impeach Obama" is the fact that it's not only possible… but he gon' do it, too!
FUN FACT!
You can retroactively impeach.
It's in case a crook was surrounded and protected by other crooks before a White Hat took the reigns.
Retroactive Impeachment = Undoing all the fuckery.
Thy expectation shall come to fruition.
