I voted for 2nd but that's the optimist in me speaking. Third is probably more likely. My mother lives in Iowa - I hope she isn't indicative of the typical Iowa voter. I've spent the last two months trying to open her eyes and she stubbornly sticks to her "I don't see him on TV so he can't win" crap. I showed her the Meetup group info to prove how large, by comparison to other candidates, his support base actually is. Her eyes glazed over. Frustrating, to put it mildly. On a more positive note, my father and two brothers are all Ron Paul supporters.
Dig up the statistics that show how unpopular the Revolutionary War was back when it was happening (I think about 50% of the population was against the idea). Sometimes doing what is right is unpopular. What matters is that you do what is right. Tell her that people like her are why we are always stuck voting for the lesser of two evils.
