Some Muni Bonds Appear Screaming Buys Here

Obviously the "muni bond insurer" issue is at the forefront of the discrepancy, but I think you have the proverbial "baby getting chucked with bathwater" thing happening, and the "unshakable economic purpose" the author references looking for seems to be very sound advice.

If the price is down simply because it's questionable the insurance wouldn't cover in the event of a default, but the reason behind the bond issuance was valid/needed/funded it seems we have some very good deals out there.
