John Ringo's The Last Centurion. Except for the assumption that Hillery is president at the time of the collapse it reads like today's headlines. Best read I have had in a long time.

John Ringo's The Last Centurion

+1. I just read that a few months ago. Not good to read if you're a liberal. I loved it.

As to a list

Patriots
Lucifer's Hammer (dated but still good)
Farnham's Freehold
Dies the Fire. The first book is a post apoc survival tale...it gets a little fruity in the next books
I've read others, I just wish I could recall them. heh.
