That's pretty far from the truth.
Stimulus-wise, he's attempting (without full support from congress - stimulus bill was too watered down to have the effect we need it to) to do exactly what most economists say you should do in the beginning of a severe recession. His approach in this department has not wavered or changed one tiny bit.
Energy-wise and health-care wise, he's doing exactly what he promised he would do in his campaign. It is exactly what the voters said they supported with their votes. It is exactly what the polls show the voters still want. Again, congress (especially the senate) isn't helping as well as it might, and Obama will probably have to sign bills that only do part of the job.
