Demonstrating the willingness to stand up to a tyrant is not a win for the tyrant.
If that tyrant, along with his complicit media paint a picture that it's just "extremist Republican and Tea Party sour grapes..." it's not much of a win for those that impeached him.
The eGOP has for too long, allowed themselves to be trampled on by Obama. Simply put, they don't know how to effectively communicate or describe how the President's agenda is bad for the United States. They don't know how to challenge his anti-Constitutional actions, and they don't know how to stay on-message.. The GOP is disjointed; its message is never crisp, never repeatable, never fully orchestrated to achieve a goal.
While I'm in agreement that impeachment is long overdue, I worry that a symbolic action by the House will be painted as overly partisan, and that failure to obtain 67 votes in the Senate play to Obama's advantage.
