This is probably because the USA is relatively large and there are significant differences between states in terms of culture and industry. For example, the people of New York probably have very little in common with those of Tennessee. For example, it's easy for a liberal in Massachusetts to label a conservative in Arizona a "bigot" for wanting to close the border, but the liberal in Massachusetts has probably never experienced the issues of illegal immigration in the way that someone from Arizona has. This is why I think more power needs to be given to individual states rather than the federal government.
