what's the deal with fannie mae and freddie mac?

is the government gonna let them go under? it seems to me like a pretty shaky scenario...dont want it to be dubbed as obama's "lehman brother".

but it also seems like an impossible situation to fix these two enterprises

Indeed, I read they fell out of NYSE (New York Stock Exchange) as well, as their shares weren't worth enough anymore. The institutions won't go under, but they might stay under complete government control for some time.
