The other side to the GOP SuperPACs:
The Incredibly Dumb Political Spending Of 2012
The upshot of it is whilst the Romney SuperPACs have a lot of money, a lot of them are run in a fragmented, disorganized manner by stupid people who don't have much idea about what they're doing. A lot of wasted money isn't much more than a lot of wasted money. It may explain why the Republican convention - which was accompanied by a barrage of ads - had much less impact than expected. Also, Romney's financial advantage may not quite be as it seems.
EDIT: And the Stewart clip is probably his best of the year, IMO.
