The Election: What Does Obama Want? What Do I Want?
Obama's (hypothetical) preferences are more interesting. Everyone takes it for granted that he wants the Democrats to do as well as possible, and it may well be true. On the other hand ... .
Suppose he believes that most of the things that are going badly now, most notably the unemployment rate and the deficit, will still be going badly two years from now. If the Democrats retain control Congress there will be nobody but the Democrats to blame, which could have negative consequences for an incumbent running for reelection. If, on the other hand, the Republicans control one or both houses ... .
Returning to my preferences, there is one more factor. The better the Republicans do, the more emphatic the public rejection of Obama's policies. Since most of the policies in question—stimulus, bailout, Obamacare, and cap-and-trade—strike me as bad ones, that would be good. It would make it less likely that later politicians will repeat what I view as his mistakes.
