The historical event that John McCain needed to take responsibility for was the removal of President George Bush and Vice President Dick Cheney from power.
Everyone knows and history will record the fact that no one (no ordinary citizen) could have predicted what President George Bush and Vice President Dick Cheney would do once they were in power.
Once it was known though it was the responsibility of the Republican Majority Leadership to remove them from power.
No one is more responsible for what has happened to our troops, our country, our world and us than Senator John McCain.
No amount of pointing the finger anywhere else will change the truth.
The slim majority currently held by Democrats cannot prevail upon the President and his Vice President to change their course without help from the current Republican Leadership.
Regardless of what happens now, John McCain will go down in history as one of a handful of individuals who could have done something, but didn't.
John McCain will be celebrated as an American who, when his country most needed him to stand up, remained seated.
