Here's where your ignorance shows...
Sure, the "right controlled" House could start impeachment, but a conviction requires ~67 votes in the Senate.
Which 19 Democrats do you expect to vote to follow the law vs. what Harry Reid asks them to do?
Even if the balance of power shifts as expected in the Senate after the mid-terms, there will still need to be 13-15 Democrats who would need to vote in favor of impeachment, and that could in turn be seen as political suicide for their own re-election.
Self-preservation is more important to politicians than ethics, so don't hold your breath.
What I would expect after the power shift is to see legislation passed by a plurality restricting where Obama has overstepped his bounds, and also looking to increase some power where administration agency officials are concerned, e.g. The VA Accountability Act that was killed in the Senate.
