The term may also be used specifically in relation to government policies that attempt to regulate matters considered to be private or personal such as private sexual behavior or individual food choices - similar to the British term 'nanny state' The term has also been used in the context of the United States to define a dominant federal government that seeks to control the authority of local institutions—an example being the overriding of state authority in favor of federal legislation.
