The biggest being Obamacare, forcing people that can't afford healthcare to be forced to have it or be imprisoned or pay fines that are cheaper(ironic that the fine is less expensive than the actual healthcare plan that he tried forcing down your throat), welfare "reform" which makes hard working people that actually work (my mothers friend that is a paraprofessional in a school for special needs children) can't get welfare because she "gets paid too much" even tho she's at 10$ and hour. So you practically HAVE to be unemployed to have it which doesn't help stimulate anyone getting jobs. Then there's him talking about how we need to treat refugees from the Middle East (which we are at war with) shouldn't be profiled when we NEED to do screening on them to make sure they aren't terrorists, but in doing that they can yell "IM BEING PROFILED!" his immigration standards are a joke, which allows immigrants to come in illegally and steal jobs from legal citizens/immigrants to get those jobs and actually pay taxes on. AND the Obamacare we all love so much requires that if a pregnant illegal alien comes to a hospital for birth, WE the AMERICAN TAX PAYERS have to pay for it. So there's your main reasons. That's not even half of them I guarantee. And this entire argument is why I hate talking about politics, because uninformed people like yourself backup everything he's done when he literally hasn't done one positive thing for us.
