Thinking it over:
From Obama's perspective, he hasn't really "lost" on any political issue, has he? Yes, nominations are stuck in the Senate and some other things haven't gotten done (e.g. climate legislation) but is there any issue where Obama put his stamp on it and it then didn't pass? Partly it's because he's let Congress do the work and so the failures, such as they are, are Reid's and Pelosi's. I wonder if that sense of a winning streak (or more accurately, not having lost) is affecting how they see the electorate, their base, and their overall situation. I bet they feel pretty good about themselves.
