Ron Paul understands the need for both social and fiscal liberty. Bernie doesn't even support either. While Bernie claims to be for liberty, he time and time again as been an interventionalist. He supported the US bombing Yugoslavia, while Paul championed to end the era of the US being the world policeman. Ron Paul understands complex economic theory while Bernie Sanders is still stuck thinking that communism is a good idea. That's why Ron Paul is America's last hope.
When Ron was asked if uninsured should be allowed to die, he said "That's what freedom is all about, taking your own risks." He didn't find a problem that his campaign manager was billed 400K in a hospital.
Bernie wants to end the international embarrassment that the US is the only major. Industrial nation without universal health care. The only nation that doesn't have maternity leave benefits, doesn't have vacation benefits. Many think that these ideas would bankrupt the country but that's not true. The US has a huge debt and median income has decreased. US has very poor education system.
In 2012, he was not only a libertarian, but also brought it to the mainstream. Bernie Sanders isn't for freedom at all, really. He doesn't want people to protect themselves, wants very high minimum wage, and wants free health care. Sanders supporters often use the argument of "It's embarrassing that we don't have universal health care. All of the other countries are laughing at us, practically." But in reality, free health care is highly destructive, and I personally would be embarrassed if I was a Canadian citizen that knew that since health care for animals was privatized, they got BETTER health care than people did! And first of all, universal health care is not "free." It's actually more expensive for everyone. Second of all, shouldn't what kind of health care you're getting be a choice? Advances in medicine and health care are advanced by competition from PRIVATE companies. If I have more money, why should I have to get crappy health care? Lastly, Sanders supports abortion, the most anti-choice and freedom killing thing there is. People say it should be a "right to chose." This is ridiculous. What about the fetus? Sanders says " It hasn't developed into a human being yet." But, really, it is a human being. Using that logic, you should be able to kill a mentally disabled person for not being developed.
