This is Mitch Daniels, the Gov. of Indiana, addressing CPAC yesterday. (Sorry, I can't find an embeddable video. Here is a non-embeddable one with good sound quality.) One part of his speech I liked very much is this:
We believe it wrong ever to take a dollar from a free citizen without a very necessary public purpose, because each such taking diminishes the freedom to spend that dollar as its owner would prefer. When we do find it necessary, we feel a profound duty to use that dollar as carefully and effectively as possible, else we should never have taken it at all.
