Consider his two signature legislative accomplishments (one 5 ½ years old, the other 4 ½ years old): The post-meltdown stimulus and ObamaCare.

These, arguably the two most expensive domestic programs ever put on the books, weren’t carefully formulated and rigorously conceived.

They were jerry-rigged assemblages of ideas, policies pulled down off the shelves of congressional subcommittees.

Because the stimulus was so poorly designed, the stimulus was used in large measure by states to pay down their own debts rather than on “shovel-ready” projects intended to employ the unemployed. And ObamaCare’s manifold sloppinesses and disasters both in the drafting and in the execution have gone off like time bombs every few months ever since the law was passed.
