The Next President sounds like it should be part of Joseph Flynn’s Jim McGill series, but is actually a stand-alone. But in any case, it’s free right now.

(Although Flynn has gone self-pub in a serious way with his own Stray Dog Press, I've read and enjoyed all or nearly all of his Jim McGill, John Tall Wolf and Ron Ketchum titles, and also some other non-series titles. I don't really notice where the books stopped being "traditionally published", so I suspect he has done a good job of getting professional editing even as he self-pubs.)

Spoiler:

J.D. Cade came home to southern Illinois from Vietnam and thought he’d never have to kill again. He was wrong. Someone starts blackmailing him. Not only does this new anonymous enemy know J.D.’s darkest secrets, he also implicates J.D.’s son in a death that could reignite a blood feud.

The blackmailer wants J.D. to use his deadly skills to assassinate Senator Franklin Delano Rawley — the first African-American with a chance to become president of the United States.

In order to save his son, spare Rawley and emerge alive, J.D. must somehow find out who is behind a conspiracy that could change the fate of a nation.
