Bob isn’t that impressed and, I know, neither are many other liberals. Among other things, they think Obama made too many compromises. The recovery act was too small. Financial reform won’t break up the big banks. Health care reform has no public option. Etc etc.

The compromises are real enough. But, to make what should be a familiar point by now, so are the political constraints. Corporate money and lobbying magnifies the power of conservatives, who already have disproportionate representation in the Senate--where, of course, it takes a ridiculously-super-majority of 60 to pass just about anything. Obama simply can’t pass legislation through Congress without compromising with conservative Democrats and (now) at least one Republican.

Bob thinks Obama could do a better job of educating the public, starting with the reality about deficits and the economy. I can see that, at least to a point. Obama could defend government more explicitly. I’m certainly getting sick and tired of that paragraph, seemingly cut and pasted into every speech, in which Obama insists he wants good government not big government. Why not just make the case for government and move on?

But I’ve always thought the president’s biggest ability to shape the political conversation is by setting the agenda--that is, by choosing what causes to embrace and then elevating them issue through his speeches and actions. Critics on the left seem to think the choice was between a pretty good plan and a spectacular one. It wasn’t. The choice was between a pretty good plan and nothing at all. Even plenty of Democrats thought Obama shouldn’t also pursue climate change and financial reform. Yet he’s continued to pursue both, albeit with varying results.

That's not to say Obama is as liberal as some of his more liberal fans (like me) want. Finding fault with his presidency isn’t impossible, or even that hard. A good starting point would be the utterly avoidable regulatory failures, documented by Tim Dickinson in Rolling Stone and Brad Plumer here at TNR, that enabled the Gulf oil spill. But those failures and mistakes are part of a bigger story, one I would have thought made more liberals proud.
