That is a pathetic analogy. Ron Paul votes against the Feds’ taxes so there is no comparison to stealing a credit card.
First, he doesn’t always vote against taxes, that is one of those lies they keep saying over and over hoping it sticks. In reality, he has voted for tax hikes before. For example, this time last year he voted for Nancy Pelosi’s tax hike proposal of the extension of the Bush tax rates (Pelosi’s proposal increased the rates on the top levels).

Second, the way earmarks work, they are not itemized lines in the budget that Congress votes on- they are riders. So it doesn’t matter if he votes against them, he is responsible for them being in the bill. He can’t wear gloves to say he wasn’t part of a robbery because his finger prints weren’t there.
