The mccain Wafffling
While we expect some consistency from those who want to be president if it seems to be missing from time to time it just might be because these folks are more interested in power than truth:
What runs consistently through John McCain’s lifetime of discourse on the use of his country’s military might is his own desire to win—not any war, but his own, personal battles. And, since the early 1980’s, those battles have been for higher and higher public office. If there appear to be inconsistencies in McCain’s positions, it is because deep down, at his core, John McCain is a man that wants above all else to be president—and his positions need to serve that ambition.
The closer it gets to election time the more politicians seem to exude this behavior.
Sometimes verbally, sometimes by their actions.
