interesting chart on 538.com

What's interesting to look at is the disparity between the red and blue dots. The [font color="#900000"]red dot[/font] is the politician's voting record, the [font color="#00a000"]blue dot[/font] is his/her public statements.

Thus, if the red is to left of the right, this politician votes closer to moderate than his rhetoric would suggest. If the blue dot is to the left, then this is a politician who talks a moderate game, but then does the bidding of rightwing interests. The wider the gap, the bigger the hypocricy.

Note the big gap in McCain's verbal "maverickism" compared to his actual performance in office. Compare to how relatively more moderate Kasich was in Congress in comparison to his more incendiary talking points. But down on the bottom, note the HUGE gap between sane talk and extremist voting by the Paul dynasty.
