You must be getting your information from Fox.  Regarding pre existing conditions. The reason Obamacare requires everyone to carry insurance (remember, this was a Heritage/GOP idea) is so that people carry insurance even when they didn't think they needed it.  So, when a crisis arises, you're not cut off by your insurance company when you get really sick.  Prior to Obamacare that's what was happening.  Or we all subsidized people without insurance going to emergency rooms.  Obamacare tries to spread the health risk over the entire population.  Much needs fixing, but most of the GOP doesn't even understand how the whole system works.  Remember Romneycare.  The republicans loved that system which is exactly what Obamacare was trying to copy.  Problem is that a black democrat proposed to implement a republican idea, and that is NOT acceptable to the Fox News lapdogs i the republican party.
