I am quite dubious of the Citizens United question, which phrases things in terms of the opinion allowing for “both sides to spend hundreds of millions of dollars in secret money to try to buy elections.” [UPDATE: This is couched in terms of what “opponents say” about the opinion. Some surely do, but they are wrong. But then the poll question does not rate what people think of the actual opinion.]
Look, I hate Citizens United (start here). But that is not at all a fair characterization of what the opinion did. Start with the fact that it endorsed disclosure and did not cause secret money. And the claim of “buying elections” is quite simplistic and misleading.
