Ok, one more time with gusto:
My question is how many of the reversals of position- not promises- are actually changes of heart or just the result of political expediency. And how does one gauge that?
Example: someone changes their position on gay rights. Is it because they actually believe in those rights or is it political expediency? Did they not support them before because that could cause political damage? There are many other issues like that.

Campaign promises aren't a good measure- for example in Obama's case there was clearly a lot of obstruction to anything and everything he wanted to do.
And there are several examples of obstruction during other presidencies as well. So that is not so interesting.
