It was funny out of context, but grounded in discussion it makes a valid point.
I don't see how anyone can claim what a politician will do when in office. What politicians want to do, what they say they want to do, and what they actually do are often very different. Instead of claiming we know what a politician will do when/if elected, it makes more sense to admit that all nominees are subject to failure in fulfilling some of their promises. I know most of us know this, I'm just bringing it up to clarify some of the "facts" being shared.
