Except for the fantasy statements, Obama is careful about actually doing anything. He's good at making sure that whatever happens, he is not held to blame.
But he does actually do some things: He pushed 'clean, green, pure, pristine, 100% all-natural energy' and got a lot of campaign contributions. He has pushed ObamaCare but seems to want to 'push' its implementation out past the end of his second term (fine with me). So, he wants ObamaCare as fantasy but not as actual implementation. He does some little things in Syria, e.g., supposedly trained about 20 rebels in how to use some Russian missiles; so, he gets to claim to support 'fighting for freedom' or some such in Syria without actually doing much or much he could get blamed for. He asks the DoD to give him options for doing more in Syria, no doubt already knowing that all the options would be high on cost and low on effectiveness and that he won't approve any of the options; but just by making public that he asked for the options he will please some voters. After one of the high school shootings, he visited the site and said he was going to 'get the guns' or some such. Of course the Second Amendment and the NRA are still there, along with a lot of gun owners in rural and Western states. But the high school shootings are out of the headlines now. We could go on and on this way.
For the NSA leak issue, he sees right away that a lot of voters are concerned about the Fourth Amendment and so makes statements, like the one to Leno, that he is against 'over reaching government' or some such. But as the Salon article explained in detail, what Obama said to Leno was just nonsense. But such nonsense is about all Obama needs because only a tiny fraction of the voters will get as deep as the Salon article, and the MSM mostly won't go there. So, superficial nonsense is enough.
Maybe it's a smart strategy. There is a danger that once people catch on that mostly he's just passing out fantasy nonsense no one should take seriously, too many voters will get pissed. Maybe. Maybe not.
At least he's not actually doing much, and money he doesn't spend isn't wasted and projects he doesn't do aren't failures. We've got plenty of government and in total don't really need more. So in a major sense, Obama can get by without doing very much. Actually I wish that at times W had done less.
There is a risk if the country actually needs a president; in the meanwhile it's okay for him to spout fantasy nonsense on Leno and work on his golf game and jump shot.
