I think most Americans are aware of how shitty the country acts. I talk to a lot of Trump voters at work, many of them think the wars in Iraq and Afghanistan were terrible, the war on terror is going awful, the cops and CIA are off their rockers. Unfortunately, a general hatred of the way the country is run and a lot of racism leads them to support Trump. His message is anti-government and anti-the way things are going, and he's racist.
Most trump supporters are lying when they say they were against wars or the CIA or anything republicans started under Bush. They did start hating those things once a black democrat was made retroactively responsible for all of them and didn’t stop them.
