It's an early exit poll, and we should obey all the important caveats about not trusting those, but since bloviation is the order of the hour, consider this from Marc Ambinder:

Who's to blame for the economy? Bankers (34%), Bush (29%), Obama (24%). Of those who blame bankers, Republicans hold an 11 point advantage.

• Matt Yglesias says, "The modern American conservative movement does not care -- even a little bit -- about the size of the budget deficit," which requires a bit of clarification, I think. The Republican Party -- demonstrably -- does not care about the budget deficit, but I'm sure some movement conservatives do as a matter of principle. But insofar as there is overlap between the party and the movement on this issue, they are each seeking different things. Republicans want power, and whining about the deficit is one way to get there.

A useful article on campaign spending for 2010 House races by Michael Luo and Griff Palmer begins by noting that in contested races Democrats have actually outraised and outspent their Republican opponents. This is not, however, the whole story:

Republican-leaning third-party groups, however, many of them financed by large, unrestricted donations that are not publicly disclosed, have swarmed into the breach, pouring more than $60 million into competitive races since July, about 80 percent more than the Democratic-leaning groups have reported spending.

Daniel Larison is still bearish on the odds that Republicans will win a majority in November:

At this point, it appears that Republicans will gain 35 seats. If all of the toss-ups broke for the Republicans, they could realistically gain 41, which would be just enough, but all of them are not going to break their way. [...] The least certain pick-ups are AR-01, ND-AL, OH-18, MI-07, NH-02, NV-03, and SC-05, but I am still assuming Republicans win these. Democratic pick-ups will include the three everyone expects in LA-02, DE-AL and IL-10, and will most likely include Hawaii’s First District and Florida’s 25th.

Republicans should heed David Frum's point about generalizing from November's elections:

Be very careful about projecting forward from the 2010 congressional results to the 2012 presidential vote. These elections almost occur in two different countries.

Be very careful about assuming that Republican success in 2010 signifies that Republicans have overcome the longer-term problems that I’ve been writing about these past five years. If Republicans cannot connect better to the huge new Millennial generation, next month’s success will only be a happy interval before 2012’s grim challenges.
