Fannie & Freddie were a business. They bought mortgages from banks/brokers. They wouldn’t have been able to do that if it weren’t economically viable for the banks/brokers to dump the mortgages. That way they didn’t have to service them all those years.
They had a market niche, and in that sense, they were valuable. I’ve probably had 4 mortgages in my life, and all except this most recent was sold. The small country bank I’m with right now likes to service their own.
I thought you understood, many of the mortgages Fannie and Freddie bought were no good, and they knew it, and Gingrich admitted that he knew it. The taxpayers have had to bail them out with tens of billions of dollars. Instead of Gingrich telling the American people of the huge liability Fannie and Freddie had become, he instead decided to publicly promote them, for money.
That's just part of his history that he has to live with.
