I do not believe impeachment would be enough for Obama. And even a conviction after the impeachment would not be enough.
Obama is like the CEO of an international conglomerate who has grafted in all his cohorts and have told them all to ignore the law and proceed with The Plan at all due speed.
They ignore any law that will not fit their scheme. And yet they smile and act as if they own the world.
Obama's breach of law is not contained to what is written in the Constitution, he has also flagrantly breached the Law of God.
Impeachment and conviction is not enough to make things right. He has offended the Holy Spirit which is the unforgivable sin.
And there is only one remedy for that.
Obama would celebrate the opportunity to go on the campaign trail to fight impeachment. Obama would fight the impeachment on the campaign trail, not in the Congress.
