I have been Rush 24/7 subscriber for years. Done with it when it expires.
Well, you can expect periodic mailers, exhorting you to re-subscribe for several months after it expires.
Mine expired in May, and I am still getting them, via snail mail. In fact, I got another just last week.
You should let Rush know now that you are not renewing and the reason why. Rush is primarily concerned with getting invited to the dinner parties and events put on by the GOPe.
