Actually, one network reported that it was disproved that his supporters were doing multi-dialing to vote for Paul. Some reporters tried it and was told: “Sorry, you’ve already voted once.”
They were not allowed to vote more than one time.
BTW, I’m not a Ron Paul supporter by any stretch of the imagination.
The voting is not phone based, but rather text message based.
Those can be sent via the internet and the Paulistians are running Perl scripts to do just that.
It’s even easier to corrupt than the American Idol voting.
