Severe Bipolarism Disorder

I think that yesterdays debate went OK for Obama.  Today Chris Van Hollen e-mailed asking for money

Wasn't it just about the day before yesterday that the risk was we would be convinced it was lost already ?

My party suffers from bipolarism disorder.

Also far from me to insult my mother's representative (my father's too) but why exactly is the chairman of the DCCC worried about overconfidence ?  The big big 0.5% lead in the generic ballot ? Or is he maybe writing to me about the presidential so I will read the e-mail, but really thinking about the congressional ?  That is his job.
