It takes a big government to run a big country. In dealing with other nations we must speak with a unified voice. We can't have Texas dealing with Mexico one way and Arizona another. Rules governing immigration, farm product importation, border security, etc. are Federal issues.
The federal government needs to be reminded from time to time about the 4th Amendment securing people's persons, homes, papers and effects from unreasonable search and seizure. The SOPA bill was really pushing the boundaries. Good it didn't pass.
Right now the Congress needs to pass the infrastructure bill and get people working again.
