The chips, indeed, are beginning to fall. They fell in Wisconsin, where Democrats failed to unseat Gov. Scott Walker in the recall election. Not incidentally, Obama was MIA in the run-up to the election. Might he have sensed that things would not go well for Democrats and thus decided to step out of the frame? When the going gets tough, the survivors vamoose.

All of which is to say, Obama has had a bad couple of weeks. Job numbers are still lousy, and the Supreme Court may soon drop a daisy cutter on the president’s signature achievement, the Affordable Care Act.

But the fact that Obama’s surrogates can’t stick to the script may be the best barometer of his perilous incumbency. In the political jungle, where people tend to be more Darwinian than divine, he is wounded and the pack is beginning to turn. Former Pennsylvania governor Ed Rendell, who could be a hockey mom if he wore lipstick, recently told CBS’s Charlie Rose that Hillary Clinton would have been a better president.

Yes, that is blood you smell.
