FHA and VA mortgage programs for high default rates, because these programs were started or expanded most under Presidents Carter and Clinton.
Yet these programs do not offer the high-risk "option ARM" mortgages that have sky-high default rates (see page 26 at
http://www.gao.gov/new.items/d0878r.pdf ). "Subprime FRM" (fixed rate mortgages) offered by these programs actually have auite low default rates (see page 10 of
http://www.frbsf.org/publications/federalreserve/annual/2007/2007annualreport.pdf ).
Also, Rs repeatedly use the term "Subprime" to encompass not only true subprime loans but also low-documentation "alt-A" loans used by speculators. This is partly a data problem, because "National Delinquency Survey" data do not distinguish alt-A but lump most of them together with subprime, but IMO most Rs who talk about the credit crisis know about this data issue and actually consciously exploit it.

The primary mortgage market has several segments and offers a range of loan products:
The prime market serves borrowers with strong credit histories and provides the most competitive interest rates and mortgage terms. In 2006, the prime market segment accounted for about 58 percent of mortgage originations (in dollar terms).
The Alt-A market (accounting for about 16 percent of mortgage originations) generally serves borrowers whose credit histories are close to prime, but the loans often have one or more higher-risk features such as limited documentation of income or assets.
The subprime market (about 24 percent of mortgage originations) generally serves borrowers with blemished credit and features higher interest rates and fees than the prime market.
Finally, the government-insured or -guaranteed market (about 3 percent of mortgage originations) primarily serves borrowers who may have difficulty qualifying for prime mortgages but features interest rates competitive with prime loans in return for payment of insurance premiums or guarantee fees. The Federal Housing Administration and Department of Veterans Affairs operate the two main federal programs that insure or guarantee mortgages.
Across all of these market segments, two types of loans are common: fixed-rate mortgages (FRM), which have interest rates that do not change over the life of the loans; and adjustable-rate mortgages (ARM), which have interest rates that change periodically based on changes in a specified index.
One of the main sources of information on the status of mortgage loans is the Mortgage Bankers Associations (MBA) quarterly National Delinquency Survey (NDS), which represents about 80 percent of the mortgage market.

The NDS provides national and state-level information on mortgage delinquencies, defaults, and foreclosures back to 1979 ...
NDS data do not separately identify Alt-A loans but include them among loans in the prime and subprime categories."
