Driehaus pissed off the voters of his district. He got himself booted, nobody else did it for him. I reside in the district that he represented. His vote for Obamacare did not sit well for the majority of his district, who are mainly Rs. I do remember seeing a billboard by the by the Susan B. Anthony list, but that did not influence my vote. I voted against him because he flip-flopped and voted for Obamacare after being heavily courted by POTUS. IIRC he is now over in Africa on a Peace Corps mission.
