OFFLINE geopoints for the entore United States needed

I need a MASSIVE number of OFFLINE geopoints for ALL USA cities (with no "neighborhoods, or points of interest). Here are some sources that I have found for OFFLINE geocodes, but i need someone to extract the geopoints for me, as I do not know how to GIS software and shapfiles. I just need the data in a Comma Delimited File format. [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] I need a good source for OFFLINE geopoints data (Longitude and Latitude) for the United States only, to be used with a Python script using the "reverse-geocode" module (with a user supplied [login to view URL] file). Online and API source will not help me because I have millions of Longitude and Latitude points to "reverse geocode", and all online sources have limitations on quantity. I have a decent sized OFFLINE geopoints file, that I purchases commercially (69,500 USA points with ZERO neighborhoods), BUT i want to get as many OFFLINE geopoints as possible to insure "reverse geocoding" accuracy. I have other larger OFFLINE geopoints files, but they have neighborhoods - I only want city names.
