A few disagreements:
Q4: How will you deal with the threat of a pandemic? you said Romney said he would strengthen public health systems. I saw nothing like that, he only talked helping companies innovate in vaccines.
Q14. Vaccination and public health. Obama emphasised the Affordable Care Act and Prevention and Public Health Fund, which are major ways of dealing with that - the implication is Romney would remove them. That is not just a boilerplate answer.
Q10 Ocean Health: This is always an interesting subject to see how somebody deals with the tragedy of the commons problems. I can't say either was really engaging with the problems but at least Obama was going to have federal involvement in trying to fix the resulting problems, rather than just monitoring the situation and giving the results to the people to let them make a bigger mess.
I view Romney's answer's to the food and drink questions as let the vendors say what's good for you and remove the regulations because they cost money.
The Romney answers about education are particularly interesting as they're not immediately obvious After all he can always pay for a good education himself. It seems to be something Romney has actually thought about. As far as I can see the idea is to give more control of teaching to the local community but also talks about better standards. Is children and their future a subject he actually does care about?
