No single group of homeschoolers speaks for all homeschoolers, and no single presidential candidate can be said to be the choice of even a majority of homeschoolers.
You may be asking why you should care, and I imagine most people here don't and likely shouldn't. Those readers are probably not aware of HSLDA or Mike Farris. HSLDA, Home School Legal Defense Association, is a group of fundamentalist lawyers that like to think they invented homeschooling and single handedly fought to make it legal. They are heroes to a number of families who homeschool for primarily religious reasons and have decided they like Huckabee.
Not that any of that matters until you find your family being spoken for by people who not only don't represent you but also don't really even have your best interests at heart. Because the fundy voice is loudest in the world of home education, it is often assumed that they are descriptive of us as a whole.
So should you happen to hear that homeschoolers support Huckabee, remember that not all of us do. The majority of homeschoolers I tend to associate with aren't even considering the republicans any more than to be scared that someone, somewhere is considering them.
I personally like Gravel and Kucinich. I won't give you the rant about them not getting the same share of air time as the other democrats and how that effects their fund raising. I won't rant about the whole rest of the democratic candidates combined don't have a tenth of the balls either of these two have.
I don't dislike Hillary, but her camp already trying to get the dirty game started doesn't help. The only way I could really vote for her would be not so secretly looking for Bill. I'm not sure about Obama. If he could prove that he could be as a good a president as he is a speaker then I'd vote for him. I liked Chris Dodd in whichever debate that I saw when he was actually allowed to talk, but when everyone keeps shoving past him to get to Hillary/Obama/Edwards, it's hard to hear him.
So, I don't support anyone right now. However Doc likes Hillary and even made a pretty button.
