My husband.
A month ago, I could have cared less about politics. I was an econ major in college and knew next to nothing about anything. 4 years and nothing. Sad, but true. Well, that's not quite accurate. I have a prettyy firm grasp of how incentives work to motivate people and why the free market is so important.
Then, about a year ago, we attened the Libertarian Convention, and a table was displaying CD's of Ron Paul's stuff and I vaguely remember my husband saying how much he liked him. And I said, "But he's a Republican and you're a Libertarian." And that was it. Still nothing.
Then the first debate came on the TV and my husband said, "I want to watch this." Whatever, I thought. I was busy doing something else (I can't remember what). But, something, somewhere finally penetrated because I remember thinking, "Wow, this guy really says all of the things I have been thinking."
I was hooked. Now I am more of a supporter than my husband and have been calling Iowans and writing letters and making signs.
