Ron Paul pretty much always wins online polls. He has a very devoted fan club. Unfortunately for him, it isn't big enough to win Primaries.
Actually, each and every primary/caucus has been plagued with voter fraud. A man in MO was filming what was happening, and the organizers brought in cops, helicopter and all, to close it down. In Clark County, NV, when a man demanded to have the votes counted, in public, and not behind closed doors, they had police escort him out, as well, though he refused, saying he has a right to see the votes, as a registered voter. For Alaska, I think, Ron Paul's campaign is officially looking into it, now that some hard evidence has apparently been brought to the surface.
You can also do a YouTube search, where a guy has a confession of an unemployed man, who admits he's paid to support Romeny.
I, and others, wonder how he can continue to win online and other raw polls (that can't be manipulated behind closed doors, or hacked, like the voter machines...youtube that as well), and not win these contests. To my knowledge, Ron Paul is the only one who has actually had US military veterans march on DC, in support of him.
