Im not a Romney supporter, but I do find myself compelled to defend him when the Left goes nut-job. I like your comments and think its the height of absurdity to see the Obama team demanding Romney reveal documents.
You're wrong. The adults who are not registered to vote were not asked the Obama vs. Romney question. See where it says "based on registered voters:" See this other question about Supreme Court favorability in the same poll, for example. It says "based on general public".
Also, the so-called Anti-Slavery people were against the spread of slavery because they did not want blacks in the new territories and states....they used anti-slavery to cover their own racism. They were no saints. They treated blacks just as bad as Southern plantation owners.
