No, Ron Paul was elected to the House.
Now that I check, not only has Dr. No never been elected to the Senate (only running once, and leaving politics for a while after losing), he lost twice on runs for the House, although there's not really a lot to say about him losing his first time standing, particularly since the incumbent had been in office for over a decade at that point. He won a special election when that member left for an appointed post, then lost re-election by a tiny margin. Ever since, he's had solid success in every House election he's been in. I really have no idea where I got the idea he'd been a Senator. He certainly SEEMS the sort to be in the Senate.
