A few of them show how successful the right has been in controlling the discussion. For instance the fact that there is a debate about a federal amendment to ban gay marriage is deplorable. But it is a part of the public debate. It is a part of the public platform of a number of the major candidates. But then a RW'r could make the same argument, reversed, in regards to the climate change or defense cuts questions. But, to be fair, each of the issues is what is in the current public debate. But in terms of question content, the questions themselves are close to neutral, and do not lead to any specific answer.
The problem with this quiz is in the answers. In a great number of the questions, the best option is "none of the above". And that's not the fault of the quiz maker, that has to do with the candidates and their stated policies.
