They actually agree on some common things more than people think
In 2001, George Bush introduced something called the 'Patriot Act' which claimed to prevent terrorism. In reality, it also increased the amount of surveillance the government had on the country and allowed the FBI to investigate what people do online without any probable cause
Every year since 2002 the Patriot Act has been voted to be renewed 100% by every member of Congress, Democrat or Republican
Which proves they both have an interest in staying in power
