This survey is just plain wrong on various things. For "are you in favour of decriminalizing drug use" for Trump, it says "no", yet he has said that legalising drugs should be studied. He has also said marijuana laws should be decided on a state by state basis. He has also accepted gay marriage and has shown no inclination he wants to change it, yet on this it makes it seem like he thinks it should be illegal again. Also, it says he thinks that government shouldn't be involved in health care, but yet he has said he has his own health care plans, whatever that means.
Who knows how many other things are wrong.
