I think Barney Frank deserves to be ridiculed and booted out of Congress for his past role in the housing mess, his continued idiocy, and this current idea which makes me believe he still has no idea what his or the government's role in the mess was (It was substantial). His main campaign contributors include the real estate sector and many financial services companies. Conflict of interest? He would say no. I strongly disagree.
Bottom Line: It is unsurprising when people react to incentives.
