Senator John McCain is no maverick.  While many of us were already aware that his carefully groomed image of going his own way was not reality, CQ Weekly did us a favor and ran the numbers.  The Methodology is as follows:

Percentage of recorded party unity votes in 2005 on which a senator voted “yea” or “nay” in agreement with a majority of his or her party. (Party unity roll calls are those on which a majority of voting Democrats opposed a majority of voting Republicans.)  (not available online without a subscription)

The results of this analysis for McCain?  He voted with the republican party 84% of the time.  Doesn’t seem so maverick, does it?
