Several arrows are still left in the quiver. Foremost are elections. All signs suggest a major defeat for Obama in November. Politicians’ minds are remarkably fungible when the people express their opinions at the polls. Not that Obama will change his mind, narcissist sociopaths rarely do. But, other politicians will and he will get no support from the Congress.
The courts can also draw the line and we have seen some early indications that they will do more. Turley is leading the charge on the legal side and he is a dedicated lefty.
If he openly defies Congress and the courts, then impeachment might be possible, provided that the people have clearly expressed a desire for such an action. To date, they have not which is why the Senate will not act even if the House does.
You do realize obama has proven there is no limit on Executive Power if you control over 1/3 of the Senate and the DOJ?
He could theoretically refuse to step down in 2016, and there isn’t a damned thing that could be done about it
