I agree with you, to a point.
If come November a conservative majority takes one or both chambers, Obama may try an overt rule-by-czars move. Or he may try a sneakier rule-by-bureaucracy move.
It will then be the duty of the House to cut of funding, and the duty of the Senate to threaten impeachment.
But if the two chambers are too timid to do this, then we must go back and try again next election.
After all, this is still a democracy. The folks in Washington really are there by the will of the majority (Yeah, I know. Money corrupts. The media distorts. Etc, etc).
But it is folly to attempt to overturn majority rule just because the majority has elected idiots or even dangerous people.
Far better to fight to change the opinions of the majority!
