“In the Iowa straw poll one can vote multible times if he is willing to pay the thirty dollars”
OK, but if Paul supporters are passionate enough to buy multiple chances to vote, I guess I would distinguish that from their being passionate enough to break the law by genuine ballot stuffing. There is a distinction between legal and illegal behavior.
I guess it depends on your definition of ballot stuffing...doing something that intentionally skews the results may not always be illegal but it is never really honest. Of course he is not the only one who does this but his followers are known for doing it consistently. And he never has voiced opposition to it. He wins a lot of polls for a candidate who seldom gets out of the single digits!!!
